Correct answer: C
The correct answer is Loader.
In a resident-OS system, some operating-system support remains in main memory so that programs can be brought into memory and started whenever required. A loader is the system software that places an executable/object program into main memory and prepares it for execution, so it must be available under all situations.
An assembler, linker, and compiler are translation or linking utilities. They are needed only when assembling, linking, or compiling a program, so they do not have to reside permanently in main memory.
