All CPU/MCU use register(s) to show the status of logical/math instructions. The are often named status or flag register(s). So yes option A is correct

What is an accumulator? An accumulator is a register.
What is a register? A register is a collection of flip-flops.
What is a flag? A flag is a flip-flop.

The correct answer is (A) Flag.
