We see more deeply into the Sun at its center than at its limb because of interaction between the light and atoms of the gas. What conclusion can be reached if the Sun appears less bright at its limb than at the center?(a) Light from the limb is reddened by solar rotation and appears cooler and therefore less intense.(b) Temperature decreases with increasing height in the solar photosphere.(c) Temperature increases with increasing height in the solar photosphere.(d) The Sun is less dense at the equator because of solar rotation.
