C Correct answer
Explanation

A 64-bit OS manages memory addresses and processes data in 64-bit chunks. The primary distinction is how it handles data in main memory (RAM), using 64-bit addresses rather than 32-bit. CPU registers are typically 64-bit too, but that's a hardware consequence. Hard disk storage format is unrelated to OS bit-architecture.
