When hormone secretion is regulated by a negative feedback mechanism, the correct statement would be:

- The concentration of a hormone remains within a narrow normal range.

Explanation:
In a negative feedback mechanism, the body regulates hormone levels by counteracting any deviations from the normal range. When the hormone concentration increases beyond the set point, the body initiates mechanisms to decrease it. Conversely, if the hormone concentration decreases below the set point, the body takes steps to increase it back to the normal range. This process helps maintain homeostasis and ensures that hormone levels stay within a narrow, optimal range for proper bodily functions.
