Task: Answer the multiple choice question.
Query: Which drug exhibits a 14.592% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cc1cc(NC2C3CC4CC(C3)CC2C4)n2nnnc2n1
b: CC1=NCCN1S(=O)(=O)c1cccc([N+](=O)[O-])c1
c: CCOc1ccc(CCNC(=O)c2ccc(F)c(S(=O)(=O)N3CCOCC3)c2)cc1OCC
d: COc1nc(N)c(C#N)c(-c2ccc(N(C)CCC#N)cc2)c1C#N
Answer: b. CC1=NCCN1S(=O)(=O)c1cccc([N+](=O)[O-])c1
