Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.158\% 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) COc1cc(NC(=O)C2CCN(c3cnccn3)CC2)cc(OC)c1
b) CCOC(=O)CNC(=S)N(Cc1ccco1)Cc1ccccc1Cl
c) CCc1ccccc1NS(=O)(=O)c1c(C(=O)N2CCCCCC2)c(C)n(C)c1C
Answer: c. CCc1ccccc1NS(=O)(=O)c1c(C(=O)N2CCCCCC2)c(C)n(C)c1C
