Final answer:
The base register is also known as the relocation register, and it's utilized in computing to help manage memory by adjusting program addresses so that programs can run correctly irrespective of their placement in memory.
Step-by-step explanation:
The base register in a computing context is also known as the relocation register. Its primary function is to hold the starting address of the memory space allocated to a program. When a program is loaded into memory, the operating system uses the value in the relocation register to modify the absolute addresses in the program so that they point to the correct locations in memory. This process is part of memory management and enables the operating system to support relocatable code, which allows a program to be executed correctly regardless of where in physical memory it is placed.
Therefore, the correct answer to the student's question is c) Relocation register.
