Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.171\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC(C)(C)c1ccc(S(=O)(=O)N2CCC(NC(=O)c3ccco3)CC2)cc1
b: O=C(Nc1ccc(Br)cc1)c1ccc(Br)c(S(=O)(=O)Nc2cccnc2)c1
c: CCc1sc(C(=O)N2CCN(S(C)(=O)=O)CC2)cc1Br
d: O=C(NCc1ccncc1)C1CCN(S(=O)(=O)c2ccccc2)CC1
Answer: c. CCc1sc(C(=O)N2CCN(S(C)(=O)=O)CC2)cc1Br
