Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.644\% 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. O=C(CSc1nnc(SCc2ccc(F)cc2)s1)Nc1ccc(C(=O)O)cc1
b. NS(=O)(=O)c1ccc(CNC(=O)c2cccnc2Cl)cc1
c. CC(C)c1ccc(N(C(=O)c2ccco2)C(C(=O)NC2CCCC2)c2cccnc2)cc1
Answer: b. NS(=O)(=O)c1ccc(CNC(=O)c2cccnc2Cl)cc1
