Choose the appropriate sentence with the Adjective Clause:

The correct answer is Option (4) → That was the reason why he came late.

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 is a group of words with its own subject and verb that describes a noun.
• It begins with a relative word:
  • who, whom, whose, which, that.
  • or a relative adverb: when (time), where (place), why (reason).
• This sentence: "why he came late" has a subject (he) and a verb (came) and describes the noun reason, so it is an adjective clause.

Why the Other Options are Incorrect?

Option 1: I have a box, filled with almonds. — Incorrect. "filled with almonds" describes the box but has no subject and finite verb. It is a participle phrase, not a clause.

Option 2: He told us the time of his arrival. — Incorrect. "of his arrival" is a phrase. The sentence has no clause apart from the main one.

Option 3: We all admire a man of courage. — Incorrect. "of courage" is an adjective phrase describing "man". It would be a clause only as "a man who has courage".

Contrast: a clause has its own subject and verb ("why he came late"). A phrase does not ("of courage", "filled with almonds").
