Choose the sentence in which the adjective clause is used correctly:

The correct answer is Option (3) → The steel lunch box that I lost on the school trip turned up in the staff room after a week.

An adjective is a word that describes a noun or a pronoun, for example a tall tree, the food is tasty.

Adjective clause:

An adjective clause describes a noun. It comes right after that noun and begins with the right word: who for people, which or that for things, when for a time. It does not repeat the noun with a word like “he” or “it”. Here “that I lost on the school trip” comes right after “the steel lunch box” and tells which lunch box.

Why the Other Options are Incorrect?

Option 1: Mausi still talks about the day where she first saw snow in Gulmarg. — Incorrect. “Day” is a time, not a place. After a noun of time the clause begins with “when”.
Corrected: Mausi still talks about the day when she first saw snow in Gulmarg.

Option 2: The scholarship went to a boy from Ranchi whose father he drives a school van. — Incorrect. “Whose father” is already the subject of “drives”, so the extra “he” says the same thing twice.
Corrected: The scholarship went to a boy from Ranchi whose father drives a school van.

Option 4: A parcel arrived for Ma from her sister which was wrapped in an old newspaper. — Incorrect. The clause describes “a parcel”, but it stands far from it, right after “her sister”.
Corrected: A parcel which was wrapped in an old newspaper arrived for Ma from her sister.
