Explanation

Despite the misleading name, a screen saver does not reduce power consumption - it keeps the display active and the GPU busy rendering animations, consuming roughly the same energy as any running office application. Options B and C incorrectly imply screen savers reduce power usage, which would only be true of actual power-saving modes (like monitor sleep or standby). Option D is wrong in the opposite direction - screen savers don't spike power usage either, since they're just standard display output like any other program.

Memory tip: A screen saver saves the screen (originally from CRT burn-in), not electricity. If energy savings matter, look for sleep mode or power management settings, not screen savers.
