A JSR instruction:

A) tells the processor to jump from the main program to a subroutine area or file.
B) tells the process to execute the fault routine.
C) latches outputs when energized.
D) latches outputs when de-energized.

JSR (Jump to Subroutine) instruction is used for calling a subroutine from the main program. When the processor encounters a JSR instruction, it saves the address of the next instruction in the stack and jumps to the specified memory location to execute the subroutine. After the subroutine is executed, the processor returns to the instruction immediately following the JSR instruction by retrieving the address from the stack.
