Question

Given below are sentences, each using the question word "happen" in different ways. Identify the sentence which uses the question word in a grammatically incorrect manner.

• A. Accept it, mistakes will happen
• B. It happened on a system that worked
• C. I promise nothing will happen to you
• D. If so happens I’m going your way

Hint:

In grammar questions, check the subject-verb construction closely. Intransitive verbs cannot be used passively or without correct subject references.

Answer 1

The Correct Option is D

Step 1: Understand the verb usage
The word “happen” is an intransitive verb. It typically doesn’t take a subject like “so” directly. So correct usage would be “If so it happens...” or “If that happens...” but not “If so happens.” Step 2: Evaluate each sentence
(A) Grammatically correct — “mistakes will happen” is a valid construction.
(B) Correct — “It happened on a system that worked” is idiomatically fine.
(C) Correct — future tense construction is used properly.
(D) Incorrect — “If so happens” is not grammatically structured. “So” cannot be used as the subject here.
