If we form a four-letter meaningful word with the 1st, 2nd, 3rd, and 5th letters from the left end of the word 'TEACHING' (using each letter only once), then what would be the third letter of that meaningful word? If no meaningful word is formed, then mark the answer as Y. If more than one meaningful word is formed, then mark the answer as W.

Correct Answer: Option T

Step-by-Step Explanation:

Step 1: Identify the specified letters from the given word

The given word is TEACHING.

Let us write down the position of each letter from the left end:

1st letter = T
2nd letter = E
3rd letter = A
4th letter = C
5th letter = H
6th letter = I
7th letter = N
8th letter = G

We are instructed to pick the 1st, 2nd, 3rd, and 5th letters from the left end:

• 1st letter = T
• 2nd letter = E
• 3rd letter = A
• 5th letter = H

The letters obtained are T, E, A, and H.

Step 2: Form a four-letter meaningful English word

Using the letters T, E, A, H exactly once each, let us check for valid English words:

• HEAT is a standard meaningful English word.

• No other standard four-letter word can be formed using these four letters.

Step 3: Determine the required letter

The word formed is HEAT.

The letters of HEAT in order are:

• 1st letter = H
• 2nd letter = E
• 3rd letter = T
• 4th letter = A

The third letter of the meaningful word HEAT is T.

Therefore, the correct answer is option T.
