The question is not clear, and the also the answer.
According to me, The question should be like "A register that holds the current instruction while it is being executed is located in ______ part of the computer ".
Now the answer can be CPU.

In computing, an instruction register (IR) is the part of a CPU's control unit that holds the instruction currently being executed or decoded. In the instruction cycle, the instruction is loaded into the instruction register after the processor fetches it from the memory location pointed to by the program counter.
