Hi, can someone please help with the following:-

Cardiologist: Coronary bypass surgery is commonly performed on patients suffering from coronary artery disease when certain other therapies would be as effective. Besides being relatively inexpensive, these other therapies pose less risk to the patient since they are less intrusive. Bypass surgery is especially debatable for single-vessel disease.

The cardiologist's statements, if true, most strongly support which one of the following?

(A) Bypass surgery is riskier than all alternative therapies.
(B) Needless bypass surgery is more common today than previously.
(C) Bypass surgery should be performed when more than one vessel is diseased.
(D) Bypass surgery is an especially expensive therapy when used to treat single-vessel disease.
(E) Sometimes there are equally effective alternatives to bypass surgery that involve less risk.
