Answer:

c. increase HDL levels

Explanation:

Cholesterol is carried in blood in two ways, LDL and HDL. Both of them are lipoproteins made of fat and protein. LDL or Low Density Lipoprotein has 50% cholesterol and 25% protein by weight. HDL or High Density Lipoprotein has 20% cholesterol and 50 % protein. LDL carries cholesterol to arteries and deposits it there which is not good for the body. HDL on the other hand removes excess cholesterol from body via liver.

Aerobic exercise increases HDL values and lowers LDL values. It has been shown that exercising regularly can increase HDL level by 6% which is good for the overall health of the body. For maximum effect 30 minutes of moderate exercise should be done 5 times a week.
