Correct answer: C

The hexadecimal system is called "Hexa-decimal" because it combines two sets of symbols:

  • Decimal Digits (0–9): The first ten values are represented by standard numbers.

  • Letters (A–F): Since we need six more symbols to reach a base of 16, the first six letters of the alphabet are used.

    • A = 10, B = 11, C = 12, D = 13, E = 14, F = 15.

This system is widely used in computer science for representing memory addresses, color codes (HTML/CSS), and MAC addresses because one hex digit can perfectly represent exactly 4 bits (a nibble).
