https://gmatclub.com/forum/in-laboratory-rats-a-low-dose-of-aspirin-usually-suffices-t-156727.html

coming to the point of the fault in option D

usage of 'to promote' is not correct. The meaning implied here in the question is 'Thromboxane promotes coagulation'
To promote on the other hand means 'To Advocate' or 'to nurture'.
