Task: Answer the multiple choice question.
Query: Which compound has a 20.477\% 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: Cc1ccc(S(=O)(=O)N(C)c2ccccc2)cc1
b: Cc1ccc(S(=O)(=O)Oc2ccccc2/C=C2\SC(=O)NC2=O)cc1
c: CCc1c(C)sc(NC(=O)c2ccc(Br)o2)c1C(=O)OC
Answer: c. CCc1c(C)sc(NC(=O)c2ccc(Br)o2)c1C(=O)OC
