Which register is concerned with the execution of instructions in a sequencing order in 8085 architecture?

a. Stack Pointer
b. Program Counter
c. Memory Address Register
d. General Purpose Register

Correct Answer : b. Program Counter

Explanation :

Program Counter is a 16 bit memory pointer which allows the sequential adoption of instructions that are to be executed & its main role is to point out the memory address which gives an idea of location for fetching the next byte. Stack pointer is also a 16 bit memory pointing register, while MAR send the address bus with address of program location under execution. GPR are the versatile registers so as to store extra additional data during the program execution.
