Task: Answer the multiple choice question.
Query: Which compound exhibits a -3.445\% 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 other words.
Options:
(a) O=C1CC(SC(=Nc2ccccc2)Nc2ccccc2)C(=O)N1c1cccc(Cl)c1
(b) CC(=O)c1ccc(NC(=O)c2noc3c2CCC3)cc1
(c) CCc1nnc(NC(=O)CSc2nnc(-c3ccccc3NC(=O)c3ccccc3)o2)s1
Answer: a. O=C1CC(SC(=Nc2ccccc2)Nc2ccccc2)C(=O)N1c1cccc(Cl)c1
