Correct option is D
The correct substitution of the highlighted words is (d)
was delighted.
Explanation: The verb “was” must be followed by a
past participle to form a passive voice or to describe an emotional state.
"Delighted" is the correct past participle of "delight."
Hence, “was delighted” is correct to express a past emotional reaction.
Grammatical rule used:
Linking verbs (like “was”) + past participle = state of being.
Example: I was delighted to see my old friend again.
