• B. (ii) and (iv)
• C. (i) and (iv)
• D. (ii) and (iii)

Answer 1

The correct option is A

(i) and (iii)

The correct option is A.

Explanation for Correct option:

1. Bones and muscles aid in the movement of our bodies
2. . The skeleton is made up of bones that are joined together. Bones are rigid and unable to bend by themselves.
3. The joints aid in the movement of the body. Muscles assist in bone mobility by pulling and contracting. Muscles conceal or wrap around bones.
4. Muscles are the soft tissue that covers the bones. They become shorter, thicker, and stiffer as a result of contraction. To move a bone, they work in pairs.
5. The other muscle relaxes when one muscle tightens to pull a bone in a particular way.
6. When a relaxed muscle shortens to pull a bone in the other way while the first remains relaxed, the bone is moved in the opposite direction.

Explanation for Incorrect option:

Option B:
Skin is the outer covering of the body and thus does not play any role in movement while organs such as the liver, and stomach have other defined functions but do not play any role in the movement.

Option C:
Bones do help in movement but the organs have no such role in the movement of the body.

Option D:
Skin is the outer covering thus does not play any role in movement while the muscles play role in the movement of the body.

Final answer: Bones and muscles play role in the movement.
