What hexadecimal value corresponds to the decimal number 10?

  1. A

  2. 10

  3. F

  4. B

The correct answer is: A

The hexadecimal system is a base-16 numbering system that uses the digits 0-9 to represent values zero through nine, and the letters A-F to represent values ten through fifteen. In this system, the letter 'A' directly corresponds to the decimal value of 10. Therefore, the correct answer is 'A', as it represents 10 in hexadecimal notation. The values 10, F, and B do not correspond to the decimal number 10; '10' in hexadecimal would represent 16 in decimal, 'F' corresponds to 15, and 'B' corresponds to 11. Thus, the only correct representation of the decimal value 10 in hexadecimal is 'A'.
