Concept:A complex sentence has one independent clause (complete thought) and at least one dependent clause (incomplete thought).
Explanation:Option C: "He reads what he likes" contains two clauses.
"He reads" is independent because it can stand alone.
"what he likes" is dependent because it does not give a full meaning by itself.
So this is a complex sentence.
Now check the other options:
A. "She lives near me" – only one independent clause. Simple sentence.
B. "Ravish did not like that bearded man" – "that" is a pronoun, not a clause. Only one independent clause. Simple sentence.
D. "Ramesh is a man of robust body" – single independent clause. Simple sentence.
Only option C has both an independent and a dependent clause.
Answer:C. He reads what he likes.
