Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.463\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. CN(C)c1nc(-c2ccccc2)[n+](C)s1.[O-][Cl+3]([O-])([O-])[O-]
b. COc1ccc(-c2cc(C(=O)NCc3cccnc3)no2)cc1
c. C=CCOC(=O)Nc1ccc(Cl)cc1NC(=O)OCC=C
Answer: a. CN(C)c1nc(-c2ccccc2)[n+](C)s1.[O-][Cl+3]([O-])([O-])[O-]
