Which option lists the symbols used in binary code?

Explanation:
Binary code uses two symbols to represent bits: 0 and 1. Computers store and process information using these two states, with each position in a binary number representing a power of two and each bit being either 0 (off) or 1 (on). That’s why the set 0 and 1 is the correct choice. The other options point to other number systems: decimal uses digits 0–9, and hexadecimal uses 0–9 plus A–F, neither of which are the symbols used in binary. A and B isn’t a valid representation of binary symbols.
