    Select the option that will improve the bold part of

    the given sentence. If he was knowing the answer , he would have told us.
    A has known the answer Correct Answer Incorrect Answer
    B knows the answer Correct Answer Incorrect Answer
    C knew the answer Correct Answer Incorrect Answer
    D had knew the answer Correct Answer Incorrect Answer

    Solution

    The verb “know” is non-continuous and is not used in the continuous form in this context.
    The sentence is conditional, referring to an unreal past situation.
    The correct structure is: If + subject + past simple, subject + would have + past participle.
    So, "If he knew the answer, he would have told us" is grammatically and contextually correct.
