Answer: Option B A hexadigit is a base-16 number system which consists of 16 digits from 0 to 15 and each hexadigit is represented by four binary (consecutive) bits. A binary number is a base-2 number system which consists of two digits, 0 and 1. Thus, four binary bits can represent a single hexadigit. Definitions: Hexadigit: A hexadigit is a base-16 number system which consists of 16 digits from 0 to 15. Binary: Binary is a base-2 number system which consists of two digits, 0 and 1. Formula: Hexadigit = 4 binary bits Explanation with Examples: For example, the hexadecimal digit ‘A’ is represented as 1010 in binary number system. Here, each hexadecimal digit is represented as four binary bits. Thus, four binary bits can represent a single hexadigit. Similarly, we can represent other hexadecimal digits using four binary bits. Hexadecimal Digits Binary Representation A 1010 B 1011 C 1100 D 1101 E 1110 F 1111 Thus, we can say that a hexadigit can be represented by four binary (consecutive) bits. Therefore, option B is the correct answer.
