Answer: (B)

The hexadecimal value for the letter 'A' is indeed 10. In the hexadecimal number system, which is base 16, the digits range from 0 to 9 and then continue with letters A to F, which represent values 10 to 15 respectively. Therefore, 'A' corresponds to the value 10 in decimal representation. This is crucial when dealing with color codes, memory addresses, and other applications in computing that utilize hexadecimal notation, as understanding these conversions is fundamental for tasks such as programming and digital system design.
