Choose the grammatically correct sentence:

The correct answer is Option (2) → Rhea is two years older than her brother Kunal, who studies in Class 8.

“Older than”, not “elder than”:

• “Older” is used to compare ages, and it is followed by “than”.

Why the Other Options are Incorrect?

Option 1: Rhea is two years elder than her brother Kunal, who studies in Class 8. — Incorrect. “Elder” is used only before a noun, as in “my elder brother”. It is never followed by “than”.

Option 3: Rhea is two years more older than her brother Kunal, who studies in Class 8. — Incorrect. “Older” is already a comparative, so “more” must go.

Option 4: Rhea is two years older from her brother Kunal, who studies in Class 8. — Incorrect. A comparative like “older” is followed by “than”, not “from”.
