What best describes the outcome of executing a JSR instruction?

Executing a JSR (Jump to SubRoutine) instruction is best described as calling another routine. When this instruction is executed, the current program's execution is temporarily halted, and control is transferred to the specified subroutine. This allows the program to perform a specific task, which could be a set of instructions designed to handle particular functions or operations without needing to write the code redundantly in the main program.

The JSR instruction also typically involves saving the return address, which allows the program to return to the point immediately after the JSR instruction once the subroutine has completed execution. This is essential for maintaining the flow of the program and ensuring that it can continue running after the subroutine execution is finished. As a result, the core functionality of the JSR instruction is its ability to enable modular programming through the use of subroutines.
