Let's look at each of the choices.
A: He had told her “You don't need to call me no more.”
There are several wrong things I can point out here. First, there is supposed to be a comma before the quotation. Also, the phrase “No more” is not in proper English. I would end up with something like this if I had to fix this sentence: "You do not need to call me anymore," he said.
B: He told her not to call him anymore.
There is nothing wrong with this option so we know this one is the correct answer. But just in case, let's look at the last two options.
C: He told her “U dont call me.”
There are several grammatical mistakes I can see happening: “U” should be spelled properly (You) and “Dont” should have an apostrophe in between the “n’ and “t”.
D: he told her stop calling.
This is wrong because the first letter is not capitalized. There should also be a “to” in between the words “her” and “stop.”
