Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.087\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(Cn1cc([N+](=O)[O-])cn1)NCc1ccc(-n2cccn2)cc1
b.) CCOC(=O)C(C)(C)Sc1nc2c(cnn2-c2ccc(Cl)cc2)c(=O)[nH]1
c.) COc1ccc(C2=NC(C)(C)Cc3cc(OC)c(OC)cc32)cc1OC.Cl
Answer: a. O=C(Cn1cc([N+](=O)[O-])cn1)NCc1ccc(-n2cccn2)cc1
