Explanation:

The body's internal "clock" mechanism related to sleep - wake cycles is the circadian rhythm. The suprachiasmatic nucleus in the hypothalamus acts as the main biological clock. The pineal gland is involved in sleep - wake regulation but is not the "clock" itself. The correct term for the brain's clock - like mechanism is "circadian".

Answer:

B. The word "clock" should be changed to the word "circadian."
