In revision A, if you read the sentence out loud you will see that it doesn't flow very well.
In revision B, the semicolon is used incorrectly. Semicolons are used to connect two independent clauses. The second sentence (the one after the semicolon) is actually a dependent clause since it's a sentence that can't stand on its own.
In revision D, the sentence is a fragment.
The correct revision is answer choice C.
It would be A. that he won't be able to find a rich woman to marry.
Hope This Helps!!
In order to properly make an argument you must state your opinion and support it with evidence
the correct answer is therefore "State what you are thinking with evidence from the text"
