Directions: Study the following seating arrangement and answer the question.

Five students A, B, C, D and E are seated in a straight row, all facing north. C sits second from the left end. B occupies the seat at the extreme right. D is immediately to the right of C. A is seated at one of the ends.

What is the position of D from the left end of the row?

The correct option is Third.

To find the position of D from the left end of the row, let us break down the given information step-by-step.

Step 1: Define the seating positions.
There are 5 students (A, B, C, D, and E) seated in a straight row facing north. Let us label the 5 positions from left to right as follows:
[1st (Extreme Left)] [2nd] [3rd] [4th] [5th (Extreme Right)]

Step 2: Determine the position of C.
It is given that C sits second from the left end.
Therefore, Position 2 = C.
Current arrangement: [ _ , C , _ , _ , _ ]

Step 3: Determine the position of B.
It is given that B occupies the seat at the extreme right.
Therefore, Position 5 = B.
Current arrangement: [ _ , C , _ , _ , B ]

Step 4: Determine the position of D.
It is given that D is immediately to the right of C.
Since C is at Position 2, the seat immediately to its right is Position 3.
Therefore, Position 3 = D.
Current arrangement: [ _ , C , D , _ , B ]

Step 5: Complete the remaining seats.
It is given that A is seated at one of the ends.
The ends of the row are Position 1 and Position 5. Since Position 5 is already occupied by B, A must sit at Position 1 (Extreme Left).
Therefore, Position 1 = A.
The remaining student, E, occupies Position 4.
Final Seating Arrangement (Left to Right): [A , C , D , E , B]

Step 6: Answer the question.
Counting from the left end of the row:
- 1st position: A
- 2nd position: C
- 3rd position: D
- 4th position: E
- 5th position: B

Thus, the position of D from the left end of the row is Third.
