Zeitgebers are external cues that help regulate the body's internal rhythms, including the suprachiasmatic nucleus (SCN) and peripheral clocks. While light is the strongest zeitgeber for the SCN, feeding patterns have a stronger effect on peripheral clocks. Therefore, option B is the most accurate description of the effects of zeitgebers on the body's internal clocks.
