• A. My father was delighted as he heard about my exam results.
• B. My father was delighted because he heard about my exam results.
• C. My father was delighted and he heard about my exam results.
• D. My father was delighted to hear about my exam results.

Answer 1

Answer: (D)

My father was delighted to hear about my exam results.

The structure of the infinitive is to+ the verb in its basic form, here, "to hear". Hence, Option D is correct. The rest of the options do not adhere to the rule, hence incorrect.
