Zeitgebers are external cues that influence the body's internal clocks. The suprachiasmatic nucleus (SCN) is the master clock in the brain that controls the internal clocks in peripheral tissues. The SCN is primarily influenced by light and helps regulate the sleep/wake cycle. Peripheral clocks, on the other hand, are located in various tissues throughout the body and are influenced by factors such as physical activity, feeding patterns, and temperature. While light is a major zeitgeber for the SCN, physical activity and feeding patterns have a greater influence on peripheral clocks. Therefore, option B is the most accurate description of the effects of zeitgebers on the body's internal clocks.
