Concept:The radix (or base) of a number system is the number of distinct digits it uses.Explanation:The binary number system uses only two digits, which are $0$ and $1$.Therefore, the total number of available digits is $2$.Since the radix is exactly the count of these digits, the radix of the binary system is $2$.This means every binary digit (bit) represents a power of $2$.Thus, the option that correctly matches the radix is $2$.Answer:C. $2$
