If a meaningful word can be formed by rearranging the letters USCALA, the first letter of the word so formed is the answer. If no such word can be formed the answer is X.
(a) C
(b) S
(c) U
(d) L

Hint: As it is given that only one meaningful word can be formed by rearranging the letters USCALA. So, we need to figure out the meaningful word and report the first letter of the meaningful word that is formed.

Complete step-by-step answer:
Let us start the solution to the above question by interpreting the question. As it is given that only one meaningful word can be formed by rearranging the letters USCALA. So, we need to figure out the meaningful word that can be formed using the alphabets U, S, C, A, L, A.
If we try to rearrange the alphabets, one word we get is CASUAL, which is a meaningful word. So, the single meaningful word asked in the question is CASUAL and its first letter is C. So, the answer to the above question is C, i.e., the first letter of the meaningful word is C.

So, the correct answer is “Option A”.

Note: Whenever you are dealing with such a question, you have to randomly arrange the letters to get the word with a meaning as we do in jumbled letters in English. There is no fixed method of solving such questions, it totally depends on your skill and knowledge of English words
