C Correct answer
Explanation

A 32-bit CPU can address 2^32 bytes of memory, which equals 4,294,967,296 bytes or exactly 4096 MB (4 GB). This is a fundamental limit of 32-bit architecture. The incorrect options (4024MB, 4000MB, 4128MB) are all close but not the correct mathematical value. This is why 32-bit systems cannot utilize more than 4GB of RAM.
