The number system that uses the most unique characters is hexadecimal.

  • Binary uses 2 unique characters: 0 and 1.
  • Decimal uses 10 unique characters: 0 through 9.
  • Hexadecimal uses 16 unique characters: 0 through 9 and A through F (representing values 10 to 15).

So, the correct answer is hexadecimal.
