Answer

Answer:

C. the tilt of the Earth’s axis and the shape of its orbit

Brief Explanations:

The tilt of Earth's axis (obliquity) and the shape of its orbit (eccentricity) affect the distribution and amount of solar - energy received, which can trigger ice - ages. Tree rings and pollen are used to study past climates, not cause ice - ages. Solar flares and ejections have short - term effects. The moon's temperature has little impact on Earth's ice - ages.
