Problem statement: Answer the multiple-choice question.
Question: Which compound has a 3.800\% 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: Cc1ccc(CCc2nnc(SCC(=O)Nc3cccc(Cl)c3)n2-c2ccccc2)o1
b: O=C(C1CCN(S(=O)(=O)c2cccc3cccnc23)CC1)N1CCN(C2CCCC2)CC1
c: CC1=C(C(=O)OC(C)C)C(c2ccc(Br)s2)NC(=O)N1C
Answer: c. CC1=C(C(=O)OC(C)C)C(c2ccc(Br)s2)NC(=O)N1C
