Consider the following statements regarding special-purpose registers.
(A) The Program Counter (PC) keeps track of the next instruction to be executed.
(B) The Instruction Register holds the address of the first instruction to be executed.
(C) The Accumulator holds the output of the ALU.
(D) The Program Counter (PC) keeps track of only the first instruction of the program.
