The temperature stability of earth’s atmosphere is mostly due to
a. the seasonal changes in day length
b. the rotation of earth about its axis
c. plant respiration
d. water in the oceans acting as a thermoregulator

I think  the correct answer from the choices listed above is option D. The temperature stability of earth’s atmosphere is mostly due to water in the oceans acting as a thermoregulator. The oceans accounts about 96.5 percent of all Earth's water. It functions as a heat sink of the Earth so that the temperature can controlled and be stable.
