Choose the appropriate sentence with the Adjective Clause:

That was the reason why he came late.

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

Option 1: "I have a box, filled with almonds."

• “filled with almonds” is a participial phrase, not a clause (it lacks a subject and verb structure).

•  Not an adjective clause.

Option 2: "He told us the time of his arrival."

• No clause modifying a noun here. Just a noun phrase: “the time of his arrival.”

•  Not an adjective clause.

Option 3: "We all admire a man of courage."

• “of courage” is a prepositional phrase, not a clause.

•  Not an adjective clause.

Option 4: "That was the reason why he came late."

• The clause “why he came late” modifies the noun “reason.”

• It tells us more about the reason — this is a classic adjective clause.

•  Correct answer
