Which of the following describes converting a binary number to hexadecimal?

• A. Binary to Decimal
• B. Binary to Octal
• C. Decimal to Hexadecimal
• D. Binary to Hexadecimal

Answer: (D)

Converting a binary number to hexadecimal is done by grouping the binary digits into sets of four because each hexadecimal digit represents four bits (2^4). Pad with leading zeros if needed, then translate each four-bit group into its hex symbol (0–9 or A–F). This mapping makes the process direct and efficient, since the bases align in powers of two. For example, binary 110010101111 groups as 1100 1010 1111, which corresponds to C A F in hex, so the result is CAF. The other ideas don’t describe this exact conversion: binary to decimal would convert using place values in base 2 to base 10; binary to octal uses groups of three bits; decimal to hex starts from a decimal value, not binary.
