Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 20.814% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=C(O)/C=C/C(=O)Nc1ccc(OC(F)F)cc1
b) Clc1ccc(CNc2ccccc2NCc2ccc(Cl)nc2)cn1
c) Cl.O=C(O)c1ccc(OCCn2ccnc2)cc1
Answer: a. O=C(O)/C=C/C(=O)Nc1ccc(OC(F)F)cc1
