This graph shows the change in the force of gravity as distance increases. the graph will never reach zero, which suggests that a) gravity cannot cross space. b) the force of gravity does not change regardless of distance. c) every object exerts gravitational force on every other object. d) more distant objects exert a stronger gravitational force on other objects

Option A

Explanation:

All objects exerts gravitational force on each other. The formula that defines the gravitational force between the two objects of mass m1 and m2 placed at a distance of "r" is equal to

Thus, until unless this distance "r" becomes infinite(cross the space)  gravitational force between two objects will never become equal to zero.

Hence, The graph will never reach zero

Option A

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
