Answer 1

Hint:When using past tense in a sentence, more than one past forms do not go together in a sentence. The reason is that no two past forms happen simultaneously, one of them would have happened before the other. (Example given in additional information).

Complete Answer:
>Option A – This sentence uses two past forms which defy the rule that two past forms should not be used together. There is an incorrect usage of grammar in this sentence; hence this is the right option.
>Option B – This sentence states that the speaker had already been aware of what has been told to them. There is no incorrect usage of grammar in this sentence; hence this is not the right option.
>Option C – This is a sentence that uses present perfect tense explaining the daily event of Mohan and Sohan going to school. There is no incorrect usage of grammar in this sentence; hence this is not the right option.
>Option D – This sentence is also an example of present perfect tense stating the fact that the person loves to teach. There is no incorrect usage of grammar here; hence this is not the right option.

The correct answer is Option (A).

Additional Information:Example: The ice-cream has melted before I could reach home and freeze it last night. Here, the melting of the ice-cream had already occurred before the person reached home.

Note: Double past forms are always unacceptable while forming a sentence. The reason is that two events cannot have the same timeline; one of them may have happened before the other, which makes only one of them exist in the past while the other is relatively further in the past.
