A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients, is cultivated in China as part of a program to integrate traditional herbal medicine into a contemporary system of health care.
(A) A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients,
(B) A derivative, which has proved useful in decreasing mortality among young leukemia patients, of the Madagascar periwinkle,
(C) A Madagascar periwinkle derivative, which has proved useful in decreasing mortality among young leukemia patients,
(D) The Madagascar periwinkle has a derivative which has proved useful in decreasing mortality among young leukemia patients, that
(E) The Madagascar periwinkle, a derivative of which has proved useful in decreasing mortality among young leukemia patients,

OA E

C is wrong because it conveys that the madagascar periwinkle derivative itself is cultivated. Madagascar periwinkle is cultivated, not its derivative

Answer is E. Note that subject in all other options is derivative of the plant...derivatives cannot be cultivated. Plants are cultivated and derivates are "Derived" from them.

(A) A substance derived from the Madagascar periwinkle, which has proved useful in decreasing mortality among young leukemia patients,----which wrongly modifies madagascar periwinkle instead of derivative & therefore changes the intended meaning

(B) A derivative, which has proved useful in decreasing mortality among young leukemia patients, of the Madagascar periwinkle,----awkward

(C) A Madagascar periwinkle derivative, which has proved useful in decreasing mortality among young leukemia patients,

(D) The Madagascar periwinkle has a derivative which has proved useful in decreasing mortality among young leukemia patients, that

(E) The Madagascar periwinkle, a derivative of which has proved useful in decreasing mortality among young leukemia patients,
C is more concise than E and is in active voice

between C and E vote for E. as above posters say derivative can`t be cultivated, but it is periwinkle

IMO C is the answer. In choice E, the which pronoun is modifying Periwinkle and not the derivative, which is the subject
