Answer:
A
Step-by-step explanation:
The coordinating conjunction "but" is used to join two independent clauses that have contrasting or opposing meanings. In this case, the first clause states that Mr. Pirzada spoiled children, while the second clause states that he only spoiled those incapable of being spoiled. The coordinating conjunction "but" helps to show the contrast between these two ideas.
The other two sentences are not correct because they do not use a coordinating conjunction to join the two independent clauses. Sentence B uses the subordinating conjunction "though," which implies that the second clause is an exception to the first clause. Sentence C is a comma splice, which is a grammatical error that occurs when two independent clauses are joined by a comma without a coordinating conjunction.
