You make a change to a C program and run the binary. When the binary is run, it produces the same results as before the change.

It seems like the change has not been honored.
Given the scenario described above, how do you fix the problem?

Choice a: Recompile the program.
Choice b: Clear the program cache and run the binary again.
Choice c: Run ./configure to reconfigure the program.
Choice d: Restart the resident set and run the program again.
Choice e: Touch the Makefile.
