Choose the grammatically correct sentence:

The correct answer is Option (2) → Our class teacher checks our diaries carefully every Monday.

Verb and object stay together:

• An adverb such as “carefully” does not come between a verb and its object.
• Here the verb “checks” is followed straight by its object “our diaries”. The adverb “carefully” comes after the object.

Why the Other Options are Incorrect?

Option 1: Ravi does not like bitter gourd, and neither I do. — Incorrect. After “neither” in a short addition like this, the helping verb comes before the subject.
Corrected: Ravi does not like bitter gourd, and neither do I.

Option 3: Kiran woke up until her alarm rang three times. — Incorrect. “Woke up” is an action that happens at one moment, so it cannot go on “until” a time. We say the action did not happen until then.
Corrected: Kiran did not wake up until her alarm rang three times.

Option 4: Nowhere I have tasted such soft idlis as in Madurai. — Incorrect. When “Nowhere” starts the sentence, the helping verb comes before the subject.
Corrected: Nowhere have I tasted such soft idlis as in Madurai.
