9. Advertisement: Clark brand-name parts are made for cars manufactured in this country. They satisfy al of our government automotive test-the toughest such tests in the world. With foreign-made parts, you never know which might be reliable and which are cheap look-alikes that are poorly constructed and liable to cost you hundreds of dollars in repairs. Therefore, be smart and insist on brand-name parts by Clark for your car.

The argument requires the assumption that

(A) Clark parts are available only in this country

(B) foreign-made parts are not suitable for cars manufactured in this country

(C) no foreign-made parts satisfy our government standards

(D) parts that satisfy our government standards are not as poorly constructed as cheap foreign-made parts

(E) if parts are made for cars manufactured in our country, they are not poorly constructed

Why D is key, how about C?
