b

c

d
When a ligament contracts, a tendon will move.

Answer 1

The correct answer is a. When a muscle contracts, a bone will move.
This describes an interaction within the musculoskeletal system. Muscles are connected to bones by tendons, and when a muscle contracts, it pulls on the tendon, which in turn pulls on the bone, causing it to move. This is how our body moves and performs actions such as walking, running, jumping, and lifting. The musculoskeletal system includes bones, muscles, tendons, ligaments, and joints, and they all work together to provide support, movement, and protection to the body.
