The correct answer is B) 232 memory locations.
An address bus is used to specify memory locations. The number of bits in the address bus determines the maximum number of unique addresses that the CPU can generate. With an n-bit address bus, there are 2^n possible unique binary combinations, each representing a distinct memory address. Therefore, a 32-bit address bus can address 2^32 memory locations.
