Answer:
The answer to your question is the second choice
Step-by-step explanation:
From the image, we discard the first option because the only planet that we observe is the earth and the description mentions all planets and the sun.
The right answer is letter B because in the image we observe the earth and the arrows that represent the force exerted by the earth downwards directed to the center of the earth.
Letter c is wrong because it mentions gravitational forces in all directions and the forces in the image go in only one direction.
Letter D is incorrect because we can see only the earth.
