Task: Answer the multiple-choice question.
Query: Which compound exhibits a 2.603% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C(NCc1ccccn1)c1cnc2sccn2c1=O
b) CN1CCC(N(C)C(=S)NC(=O)c2ccc([N+](=O)[O-])cc2)CC1
c) CC(C)(C)NS(=O)(=O)c1cnc(Cl)c(Cl)c1
d) O=C1CCc2ccc(NS(=O)(=O)c3ccc(F)cc3)cc2N1
Answer: c. CC(C)(C)NS(=O)(=O)c1cnc(Cl)c(Cl)c1
