The correct answer is D. 32.
The address bus is a set of lines that carries the address of a memory location to the memory controller. The size of the address bus determines the maximum amount of memory that can be addressed by the processor. The 80286 has a 32-bit address bus, which means that it can address up to 4GB of memory.
Option A is incorrect because the 80286 has a 32-bit address bus, not a 20-bit address bus.
Option B is incorrect because the 80286 has a 32-bit address bus, not a 24-bit address bus.
Option C is incorrect because the 80286 has a 32-bit address bus, not a 16-bit address bus.
