What are the possible values for a single hexadecimal digit?

• A. 0-9 and A-F
• B. 1-9 and A-Z
• C. 0-15
• D. 0-255

Answer: (A)

A single hexadecimal digit represents values in base 16, which means it can take on 16 different values. The range of these values includes the numbers 0 through 9, which represent the decimal values zero to nine, and the letters A through F, which represent the decimal values ten to fifteen. Therefore, the possible values for a single hexadecimal digit are indeed 0 through 9 and A through F, making the first choice the correct one. The other options do not accurately describe the range of values for a single hexadecimal digit. The second option suggests a mix of decimal and alphabetic characters that extends beyond the appropriate range and does not include all necessary hexadecimal characters. The third option implies numeric values that suggest a decimal system rather than hexadecimal, and likewise, the fourth option suggests a much broader interpretation of numbers that is beyond the scope of a single hexadecimal digit.
