Four meaningful words are given in the options you have to check that which of the following words cannot be formed from the letters.

'REASONABLE'

This question was previously asked in
SSC CHSL 2025 Tier 1 Question Paper (21-Nov-2025) (Shift 1)
The correct answer is

BRAIN

This is a word-formation question: a word can be formed only if every one of its letters is available in the source word REASONABLE.

First list the letters supplied by REASONABLE, noting repeats: R, E, A, S, O, N, A, B, L, E. So we have two A's, two E's and one each of R, S, O, N, B, L.

Test ARSON. It needs A, R, S, O, N, and each of these appears in the pool, so ARSON is a valid word.

Test NOBLE. It needs N, O, B, L, E, all of which are present, so NOBLE can also be formed.

Test BOES. It needs B, O, E, S, all available, so this too can be formed.

Test BRAIN. It needs B, R, A, I, N. The pool has B, R, A and N, but the letter I never occurs in REASONABLE, so BRAIN cannot be built.

The rule is that a target word is impossible the moment it demands even one letter absent from the source. Hence the word that cannot be formed is BRAIN.
