Identify the part of the sentence that contains a grammatical error.

A. The reason for his failure B. is because he C. didn't study D. for the exam.

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

is because he

The noun 'reason' already expresses cause, so following it with 'because' repeats the same idea. This is a well-known redundancy error: 'The reason ... is because'.

The correct construction is The reason ... is that, giving: The reason for his failure is that he didn't study. The segment 'is because he' therefore contains the error.

The other segments are fine: 'The reason for his failure' is a correct noun phrase, 'didn't study' is a correct past negative, and the closing phrase is a correct prepositional phrase.

Hence, is because he.
