Why He Didn't Come to the Meeting: Grammar Explanation

This is the reason 'that' he didn't come to the meeting.

A. which B. with which C. that D. for which

Explanation:

The correct answer is C. that. Here's why:

• 'That' is used as a relative pronoun to introduce a defining relative clause. This clause provides essential information about the noun 'reason.' The clause tells us specifically what reason he didn't come to the meeting.
• 'Which' is also a relative pronoun, but it typically introduces non-defining relative clauses. These clauses provide additional information that isn't strictly necessary to understand the main sentence. 'Which' is not appropriate in this context because the clause is defining.
• 'With which' and 'for which' are not grammatically correct in this sentence because they don't fit the grammatical structure of a relative clause. They are used to introduce prepositional phrases, not clauses.
