Which of following alphabet can not be part of a hexadecimal digit ?

  • A.A
  • B.L
  • C.F
  • D.E

Answer: B

Correct answer: L

Hexadecimal is base 16, so it needs sixteen digits: 0 to 9 for the first ten values and then A, B, C, D, E and F for ten to fifteen. The letters stop at F, so L can never appear in a hexadecimal number.
