Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -2.790\% 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: NS(=O)(=O)c1ccc(CCNC(=O)C2CCCN(S(=O)(=O)c3cccnc3)C2)cc1
b: COc1cc(-c2cccs2)cc(=O)c2c(C)oc(C)c12
c: CC(C)(C)c1ccc(OCc2nc(-c3ccccn3)no2)c(Br)c1
Answer: b. COc1cc(-c2cccs2)cc(=O)c2c(C)oc(C)c12
