Why each option

A byte is a fundamental unit of digital information, universally composed of 8 bits.

A4

4 bits constitute a nibble, not a byte.

B8Correct

By definition in computer science, a byte is a unit of digital information that most commonly consists of eight bits, which is the smallest addressable unit of data for many computer architectures.

C16

16 bits constitute two bytes or a word in some architectures, not a single byte.

D1,024

1,024 is the number of bytes in a kilobyte (KB), or 1,024 bits in a kilobit (Kb), depending on context, not the number of bits in a single byte.
