If it is possible to make a meaningful word with the first, the twelfth, the fifteenth and the twenty-first letters, then which of the following will be the first letter of that word? If no such word can be made, give X as your answer and if more than one such words can be made, give T as your answer.
None of these
The 1st, 12th, 15th and 21st letters are E, A, S and L respectively. Clearly, two words may be formed - SALE, SEAL.
