Directions: The undergiven sentence has been divided into three parts (A), (B) and (C). One of these parts may contain an error. You have to mark that part. If there is no error, mark (D).

Owing to wrong company (A) he was spending (B) his money on vice. (C) No error (D)

The error is in part (C) 'his money on vice'. The phrase 'Owing to wrong company' provides a reason or cause, which should be followed by its effect, not another action happening at the same time. The correct construction should be 'Owing to wrong company, he spent his money on vice' (simple past) or 'he has spent his money on vice' (present perfect). The continuous tense 'was spending' doesn't logically follow the causal structure established by 'Owing to'. The tenses are mismatched for the causal relationship being expressed.
