If we form a five-letter meaningful word by using the 2nd, 5th, 6th, 7th and 11th letter from the left end of the word ‘ APPLICATION’ (Using each letter once) , then which of the following will be the fourth letter of the meaningful word thus formed. If more than one word is formed then mark Z as your answer. If no meaningful word is formed, mark X as your answer.

The correct answer is Option I (which corresponds to the letter I).

Step 1: Identify the given word and letter positions
The given word is APPLICATION.
Let us write down the letters along with their positions from the left end (1-indexed):

1st letter: A
2nd letter: P
3rd letter: P
4th letter: L
5th letter: I
6th letter: C
7th letter: A
8th letter: T
9th letter: I
10th letter: O
11th letter: N

Step 2: Extract the specified letters
We need to extract the 2nd, 5th, 6th, 7th, and 11th letters from the left end:

• 2nd letter = P
• 5th letter = I
• 6th letter = C
• 7th letter = A
• 11th letter = N

The set of letters obtained is: P, I, C, A, N.

Step 3: Form a meaningful five-letter word using each letter exactly once
Using the letters P, I, C, A, and N, the only valid five-letter English word that can be formed is:
PANIC

Step 4: Determine the fourth letter of the word
In the word PANIC:
1st letter = P
2nd letter = A
3rd letter = N
4th letter = I
5th letter = C

Thus, the fourth letter of the meaningful word formed is I.
