Answer is Wrong!
The answer is B. Microphone.
A microscope is an instrument used to magnify small objects. A microphone is an instrument used to convert sound waves into electrical signals. Microfilm is a photographic film used to record images of documents at a reduced size. A microbe is a tiny living organism that can only be seen with a microscope.
Microphones, microfilm, and microbes are all related to the concept of smallness. However, a microphone is not a device that is used to magnify small objects. It is a device that is used to convert sound waves into electrical signals. Therefore, it is the odd number/letter/word from the given alternatives.
