The correct answer is C. 4GB.

A 32-bit operating system can address up to 4GB of memory. This is because 32-bit systems use 32-bit memory addresses to access memory locations. Each memory address points to a unique memory location in the computer's RAM (Random Access Memory).

The 32-bit memory addressing scheme allows for 2^32 memory addresses, which is equal to 4GB of memory (2 to the power of 32 equals 4,294,967,296, which is the number of unique memory addresses a 32-bit system can access).

So, any system that has more than 4GB of memory installed cannot be fully utilized by a 32-bit operating system. To access more than 4GB of memory, a computer must have a 64-bit operating system installed. 64-bit systems can access up to 16 exabytes of memory (which is 16 million terabytes).

To summarize, the memory limitation of a 32-bit operating system is 4GB, and any computer that has more than 4GB of memory installed must have a 64-bit operating system installed to fully utilize the additional memory.
