Read the following information carefully and answer the question that follows.

Nine students scored different marks in a test. G's score is immediately lower than E's score. Three students scored marks between G and D. I's score is immediately higher than B's score and immediately lower than D's score. Five students scored marks between E and I. H scored a higher score than E. A scored higher than C but lower than G. F scored lower than C but higher than D.

Who among the following scored the third lowest marks in the test?

To determine who scored the third lowest marks in the test, let us arrange all nine students in descending order of their scores from position 1 (highest) to position 9 (lowest).

Step 1: Analyze the given conditions step-by-step.

1. G's score is immediately lower than E's score: This means E and G are placed together as (E, G).
2. I's score is immediately higher than B's score and immediately lower than D's score: This means D, I, and B are placed together as (D, I, B).
3. Five students scored marks between E and I: Since E is above G, E must be above I. With 5 students between E and I, the positions of E and I will have a difference of 6 (i.e., Position of I = Position of E + 6).

Step 2: Determine the positions of E, G, D, I, and B.

If E is at position 1:
- G is at position 2.
- Since 5 students are between E (1) and I, I must be at position 7.
- Since (D, I, B) are consecutive, D must be at position 6 and B must be at position 8.

Now, let us check the condition: "Three students scored marks between G and D".
- Position of G = 2
- Position of D = 6
- Students between G and D are at positions 3, 4, and 5, which is exactly 3 students. This perfectly matches the condition!

So far, our arrangement from 1 to 9 is:
1. E
2. G
3. _
4. _
5. _
6. D
7. I
8. B
9. _

Step 3: Place the remaining students (H, A, C, F).

4. H scored a higher score than E: Since E is at position 1, wait, H must be higher than E. This means E cannot be at position 1 unless H is at position 1 and E shifts down. Let's re-verify the positions with H higher than E.

Let's shift the positions down by 1:
1. H
2. E
3. G
4. _
5. _
6. _
7. D
8. I
9. B

Let's re-verify all conditions for this arrangement:
- H is higher than E: Position 1 (H) > Position 2 (E) - Valid.
- G is immediately lower than E: Position 2 (E), Position 3 (G) - Valid.
- Five students between E and I: E is at 2, I is at 8. Positions between them are 3, 4, 5, 6, 7 (5 students) - Valid.
- I is immediately higher than B and immediately lower than D: D is at 7, I is at 8, B is at 9 - Valid.
- Three students between G and D: G is at 3, D is at 7. Positions between them are 4, 5, 6 (3 students) - Valid.

Now let's place the remaining students: A, C, F into positions 4, 5, 6.
- "A scored higher than C but lower than G": So A > C, and A is lower than G (position 3).
- "F scored lower than C but higher than D": So C > F, and F is higher than D (position 7).
- Combining these: G > A > C > F > D.
- Therefore, the positions 4, 5, and 6 must be filled by A, C, and F respectively:

Position 4: A
Position 5: C
Position 6: F

Step 4: Final complete ranking from highest (1) to lowest (9):

1. H (Highest)
2. E
3. G
4. A
5. C
6. F
7. D
8. I
9. B (Lowest)

Step 5: Identify the third lowest marks.

Counting from the lowest:
- 1st lowest: B (Position 9)
- 2nd lowest: I (Position 8)
- 3rd lowest: D (Position 7)

Therefore, D scored the third lowest marks in the test.
