The answer is B.
This is because it shows someone saying something, but it is what the writer has told us as an audience not a normal quotation that we see in a book.
For example, a direct quotation would be:
"Mom! I don't want to do my homework now!" Darren complained.
This is because we can see the exact words of what Darren said.
Whereas an indirect quotation would be:
Darren told his mom he didn't want to do homework now.
- Because we have to trust the writer what Darren said but cannot see the exact words.
