The correct answer is "A". 'Gravity'. The Sun's gravity pulls on the planets to keep them in motion. Just like the Earth does to the moon.

Brainliest answer is always appreciated!
Chemical stimuli are molecules that cause a response at a cellular level primarily through cellular receptors. This happens all the time in nature - cells communicate with one another through chemical messaging. An example is an aroma molecule, such as the scent from a flower. This particular molecule is detected by the olfactory cells (those associated with the sense of smell) in your nose, producing a chemical reaction that ultimately leads to you consciously experiencing the smell.
B. 100% sure
Have a good day/night
