Select the most appropriate meaning of the underlined idiom in the given sentence.

I want you to give me this contract in black and white.

in writing

The answer is in writing.

The idiom "in black and white" means in writing, as opposed to being spoken or implied. It is often used to emphasize the importance of having something in writing, so that there is no ambiguity or confusion.

In the sentence "I want you to give me this contract in black and white," the speaker is asking for the contract to be written down, so that they can have a physical copy of it. This is important because it will provide them with a clear and unambiguous record of the terms of the contract.

The other possible meanings of the idiom "in black and white" are not relevant in this context. "Quickly" does not make sense, as the speaker is not asking for the contract to be delivered quickly. "In the morning" and "at night" are also irrelevant, as the speaker is not specifying a time of day.
