Who gave you the money?

The correct answer is choice (B). Choice (A) is grammatically incorrect as it mentions ‘by who was you’. The use of ‘was’ after ‘you’ makes the sentence incorrect and it should be replaced with ‘by who were you’. The formation of the sentence in choice (C) is incorrect as it mentions ‘money to you’. It can be corrected to ‘who gave you the money’, but that would change the sentence into passive voice. Choice (D) is logically flawed as it says that someone got the money from you, yet asks who gave the money.
