The addressing mode/s, which uses the PC instead of a general-purpose register is : 

The correct answer is Relative.

Key Points

• In computer architecture, the relative addressing mode uses the Program Counter (PC) instead of a general-purpose register to determine the address of the next instruction.
• This mode calculates the effective address by adding a constant value (offset) to the current value of the PC.
• It is commonly used in branch instructions where the target address is specified relative to the current instruction location.
• The relative addressing mode helps in writing position-independent code, which is useful for creating relocatable object files.

Additional Information

• Relative addressing mode is often used in loop control and conditional branch instructions.
• It simplifies code generation in assemblers and compilers by allowing more flexible code placement.
• It can enhance program security by making it more challenging for malicious actors to predict exact memory addresses.
• Examples of assembly instructions using relative addressing include conditional jumps like JZ (Jump if Zero), JNZ (Jump if Not Zero), etc.
