Directions : Fill in the blank with correct option to make a proper sentence.
If she about his financial situation, she would have helped him out.
Explanation
The correct answer is (c) had known.
Explanation:
This is a Third Conditional sentence, which is used to express regret or discuss an imaginary past situation that did not actually happen. The grammatical structure for this type of sentence is fixed:
If + Past Perfect (had + V3),…would have + Past Participle (V3)
In this sentence, the result clause "she would have helped" is already given. Therefore, the "if-clause" must be in the Past Perfect tense. Since the verb is "know," the correct form is "had known."
Comparison of Clauses:
Condition: If she had known (Past Perfect)
Result: she would have helped (Would have + V3)
