Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 16.783\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCCCc1ccc(NC(=O)COc2ccc(C(=O)Nc3ccccc3OCC)cc2)cc1
b: O=C1CCCC2=C1C(c1ccncc1)Nc1ccccc1N2
c: COc1cc(CC(=O)Nc2ncc(C)s2)cc(OC)c1OC
Answer: c. COc1cc(CC(=O)Nc2ncc(C)s2)cc(OC)c1OC
