Where

F represents the force of gravity between two objects having mass

represents the masses of the two objects

G represents the gravitational constant which is equal to

and r represents the distance between the two objects.

Hence, the correct answer is option A

because the light is a great source of energy for the plants to survive. (i hope this )
