C I do not know that what his father's name is
D I do not know that what father's name is his
Solution
Correct Answer: Option C
complex sentence : "I do not know what his father's name is"।
Independent clause: "I do not know" - এটি মূল বাক্য বা স্বাধীন clause।
Dependent clause: "what his father's name is" - এটি subordinate clause যা what দ্বারা যুক্ত হয়েছে। এখানে "what" একটি relative pronoun, যা বাক্যকে complex sentence হিসেবে গঠন করতে সাহায্য করছে।
