Question

Fill in the blank with a suitable option:
____________________ was clear from his letter.

• A. He was angry
• B. He resented being treated rudely
• C. That he was not interested
• D. What I knew

Answer 1

Answer: (C)

That he was not interested

Noun clauses begin with wh-words like “what” and conjunctions like “that”, and act as noun, here disinterest in a particular matter. Hence Option C is correct. The rest of the options do not act as a noun, hence incorrect.
