If a meaningful word is formed using the second, fifth, sixth, and twelfth letters (from the left end) of the word “CHOCOLATEBOY”, which of the following will be the second letter from the left end of the meaningful word formed? If more than one such word can be formed, mark Z as your answer. If no meaningful word is formed, mark X as your answer.

The correct option is O.

Let's find the specified letters from the left end of the given word "CHOCOLATEBOY":

1^st letter = C
2^nd letter = H
3^rd letter = O
4^th letter = C
5^th letter = O
6^th letter = L
7^th letter = A
8^th letter = T
9^th letter = E
10^th letter = B
11^th letter = O
12^th letter = Y

The selected positions are:

• 2^nd letter = H
• 5^th letter = O
• 6^th letter = L
• 12^th letter = Y

The letters obtained are H, O, L, and Y.

Using these four letters, only one meaningful English word can be formed, which is "HOLY".

Now, we need to find the second letter from the left end of the word "HOLY":

• 1^st letter from left = H
• 2^nd letter from left = O
• 3^rd letter from left = L
• 4^th letter from left = Y

Therefore, the second letter from the left end of the meaningful word formed is O.
