The size of Yes No field is always A. 1 bit B. 1 byte C. 1 character D. 1 GB

The correct answer is A. 1 bit.

A bit is the smallest unit of information in computing. It can be either a 0 or a 1. A byte is made up of 8 bits. A character is made up of 1 or more bytes. A GB is 1024 MB, or 1,073,741,824 bytes.

A Yes/No field is a field that can only contain one of two values: Yes or No. This means that it can only store one bit of information.

The other options are incorrect because they are larger than 1 bit. A byte is made up of 8 bits, a character is made up of 1 or more bytes, and a GB is 1024 MB, or 1,073,741,824 bytes.
