Hexadecimal digits represented 1 to 9 and A to:a)Cb)Fc)Bd)DCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

The system uses 10 numerical digits and 6 alphabets –0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, A, B, C, D, E, F.

The Hexadecimal numbering system uses the Base of 16 system and is a popular choice for representing long binary values because their format is quite compact and much easier to understand.
Being a Base-16 system, the hexadecimal numbering system, therefore, uses 16 (sixteen) different digits with a combination of numbers from 0 through to 15. In other words, there are 16 possible digit symbols.
However, there is a potential problem with using this method of digit notation caused by the fact that the decimal numerals of 10, 11, 12, 13, 14 and 15 are normally written using two adjacent symbols.
To get around this tricky problem hexadecimal numbers that identify the values of ten, eleven, twelve, thirteen, fourteen, and fifteen are replaced with capital letters of A, B, C, D, E and F respectively.
