Choose the grammatically correct sentence:

The correct answer is Option (1) → Tara is two years older than I am, yet we are in the same dance class.

Subject form after “than” when a verb follows:

In “older than I am”, the pronoun is the subject of the verb “am”. So it takes the subject form “I”, not “me”. The rest of the sentence has no error.

Why the Other Options are Incorrect?

Option 2: The kitten knocked over it’s bowl of milk on the kitchen floor. — Incorrect. The given sentence writes “it’s bowl”. “It’s” means “it is” or “it has”. The word for belonging to it is “its”, with no apostrophe.
Corrected: The kitten knocked over its bowl of milk on the kitchen floor.

Option 3: Three students absented from the chemistry practical without giving a reason. — Incorrect. The verb “absent” always needs a reflexive pronoun after it. The students kept away, so it must be “absented themselves”.
Corrected: Three students absented themselves from the chemistry practical without giving a reason.

Option 4: The teacher divided the stage work among Riya, Kabir and I. — Incorrect. The given sentence says “among Riya, Kabir and I”. A pronoun after a preposition takes the object form, so “I” must be “me”.
Corrected: The teacher divided the stage work among Riya, Kabir and me.
