els and are necessary to maintain healthy cholesterol levels,
although some patients with the highest levels of cholesterol
must undergo drug treatment to bring their cholesterol to a
manageable level.

A. Individuals who do not have the highest level of LDL cholesterol
should not undergo drug treatment.
B. Lifestyle changes do not lower levels of LDL cholesterol as
drastically as does drug treatment.
C. The only ways of lowering LDL cholesterol are through lifestyle
changes and drug treatment.
D. Individuals with high levels of LDL cholesterol cannot maintain
healthy cholesterol levels through drug treatment alone.
E. Only lifestyle changes are necessary to treat patients who do not
have the highest levels of LDL cholesterol.

If you choose a choice please explain why.
