Correct option is C
A register that can work with either serial or parallel inputs/outputs and shift data either right or left is called a universal shift register.
Explanation:
· Universal shift registers can shift data in both directions and load data in parallel.
· They are made up of flip-flops and multiplexers.
· They can operate in different modes, such as no shift, shift right, shift left, or parallel load.
· They are used as memory elements in computers.
