Question

    In each question below, a sentence is given with a part

    of it printed in bold type. That part may contain a grammatical error. Each sentence is followed by phrases A), B) and C). Find out which phrase should replace the phrase given in bold to correct the error, if there is any, and to make the sentence grammatically meaningful and correct. If the sentence is correct as it is and ‘ No correction is required’ , mark 4) as the answer. If she would have known about the issue earlier, she could have helped you.
    A would know of the Correct Answer Incorrect Answer
    B had known about the Correct Answer Incorrect Answer
    C would have known of the Correct Answer Incorrect Answer
    D No correction required Correct Answer Incorrect Answer

    Solution

    The correct structure for a third conditional sentence (which talks about hypothetical or unreal situations in the past) is "If + past perfect, + would have + past participle." Therefore, "had known about the" is the correct choice as it follows this pattern, indicating that if she had known earlier, she would have been able to help.
