A bit can have a binary value of which of the following?

A bit, which is the most basic unit of data in computing, can indeed have a binary value of 0 or 1. This binary system is foundational in digital electronics and computer science, as bits are used to represent the two possible states of a system – typically corresponding to off (0) and on (1).

The other options involve either numeric values or hexadecimal representation, which are broader concepts encompassing multiple bits. For example, numeric values between 0-9 signify a decimal range, which requires at least four bits to express, while 0-9 and A-F correspond to hexadecimal values, requiring four bits to represent each digit. The description of "On or Off" can be seen as a conceptual understanding of a bit’s binary value but doesn't express the firm numerical definition of how bits are represented in binary.

Focusing on the binary definition, 0 and 1 succinctly and accurately encapsulates what a single bit can represent.
