Answer 2

The answer is c) had happened.

I couldn't find out what had happened.

• In the given sentence, we need to choose the correct tense from the given options.

• The sentence shows two actions happening. In such a case, the initial action takes a past perfect tense.

• Since the simple past tense is already given, the other blank will take a past perfect tense.

• 'Had happened' is in the past perfect tense.
