I got "A" although that may not be the OA.

If the OA is "E", it still sounds awkward [to me]...

"The Madagascar periwinkle, a derivative of which..."

What exactly is the derivative, is it the periwinkle, or is it the Madagascar periwinkle? If the Madagascar periwinkle is the derivative, then it's a derivative of what?

@graghukalyan: OA please.

OA=E, although it still seems akward to me. :

Still not clear why (C) is not correct . Please explain
