Twisting or pulling a muscle or tendon can result in a strain. It can also be caused by a single instance of improper lifting or by over stressing the back muscles. A chronic strain usually results from overuse involving prolonged, repetitive movement of the muscles and tendons. In addition, there are several factors that put a person at greater risk for a back strain or sprain, including excessively curving the lower back, being overweight, having weak back or abdominal muscles, and tight hamstrings (muscles in the back of the thighs). Playing sports that involve pushing and pulling—such as weightlifting and football—also increases the risk of a low-back injury. Chronic strains happen slowly over time from prolonged, repetitive overuse of muscles. Chronic strains develop from using the same muscle groups in the same pattern, causing even small stresses to build on one another. Causes of chronic strain include:
Improper body mechanics or using the wrong muscle groups for a task, such as repeatedly lifting heavy objects using your back instead of your legs
Improper sports mechanics or techniques, such as habitually gripping a tennis racket too tightly or an incorrect golf swing
Participation in the same exercises in the same way, day after day
Poor posture
Use of the wrong equipment, such as running shoes without the proper support for your foot type

Both C and D
Explanation:
Anorexics don't want to be fat so they take an excessive amount of laxitives and diet pills. That is answer C.
But they also look like skeletons so they hide under bulky clothing so there is your extreme weight loss, over-exercising and they obsess over food consumed. They play with their food on the plate rather than eat it. Look up Karen Carpenter. She was a very successful singer but suffered from anorexia and died from it. She had it all and still thought she was too fat. She hid under bulky clothing and played with her food rather than eat it.
