Answer:
D.drinking water
Step-by-step explanation:
Fluid filled sacs that work as cushion between bones, muscles and tendons specially in joints are called as bursae. Inflammation of bursae leads to bursitis which is caused by overuse, injury or an infection which decreases the lubrication in the joints, for example: tennis elbow.
Rest often heals bursitis so unnecessary movement should be avoided. Pads and cushions can also be used to protect the affected body part and reduce the pressure. Warming up and cooling down is also suggested before and after a physical activity respectively as they reduce the strain on joints and can prevent bursitis. Drinking water however has no direct affect on the condition.
