Which description explains how inertia changes the effects of gravity on objects in the solar system?

The answer is; D

Inertia is the tendency of an object to resist change to its velocity and direction.  The bigger the mass of an object the higher its inertia. In space, the celestial bodies with a bigger mass have more inertia and have a higher gravitation pull (because they bend space-time more than smaller objects). The gravitational force of bigger objects influences on other celestial bodies and beats their inertia force by causing them to change direction and speed.    

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
