Answer:
B. Bones provide structure and support to the body, while muscles move the bones.
Explanation:
Let's try to eliminate choices.
A: "Muscles provide structure and support to the body, while bones move the muscles."
Muscles actually aren't the ones that provide support for our body; it's the bones and our skeletons that do that. So, this is wrong.
B: "Bones provide structure and support to the body, while muscles move the bones."
Bones do, in fact, provide structure to our bodies, and muscles are the ones that attach to the bones through tendons and help move them. So, B is correct.
C: "Bones send signals to the body, and muscles are responsible for movement."
While it's true that muscles are responsible for movement, bones do not send signals to the body; that's the nervous system's job. C is wrong.
D: "Muscles send signals to the body, and bones are responsible for movement."
Again, muscles don't send signals; neurons do. D is wrong.
The answer is B.
