The right answer is Joints (or ligaments more precisely).
Muscle is the contractile structure that produces strength. It has components that allow it to be shortened to create what is called a muscle contraction.
The joint is junction of two parts of the skeleton allowing them relative mobility.
The ligament is an elastic structure that stabilizes the joints. It therefore attaches from one bone to another.
D. Bc it’s not too long of a time to stretch out of your day and it’s almost everyday so your body adjusts to your body muscles being pulled. It’s good to stretch
