   A developer writes a program that allocates memory in a loop without freeing it. The system has 16 GB of RAM. After running for an hour, the program crashes with an 'out of memory' error, but the rest of the OS remains stable. Which OS component is MOST directly responsible for this outcome?

   • AThe device driver for RAM, which failed to handle the allocation requests
   • BThe file system, which ran out of space for the page file
   • CThe process scheduler, which stopped giving CPU time to the program
   • DThe memory manager, which isolated the process and terminated it when it exceeded its allocation
