The correct answer is C. Verbatim.
Verbatim means “word for word.” It is used to describe something that is copied exactly, without any changes. For example, if you are asked to write a verbatim transcript of a meeting, you would need to write down everything that was said, without adding any of your own thoughts or opinions.
The other options are not as accurate as verbatim. Copying means to make a copy of something, but it does not necessarily mean that the copy is exact. Mugging is a crime that involves stealing something from someone, usually by force. Photostat is a type of photographic reproduction that produces a black-and-white image.
In conclusion, the correct answer to the question “Word for word reproduction” is C. Verbatim.
