Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 15.772\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.

b: CCc1nc(C)cn1S(=O)(=O)c1cc([N+](=O)[O-])ccc1Cl
c: CS(=O)(=O)c1cnc2c(-c3ccc(F)cc3)cnn2c1N
d: CC(C)(C)c1cc(N2CCOCC2)n2ncc(-c3ccc(Cl)cc3)c2n1
e: O=C(NCC1CCS(=O)(=O)C1)NCC1CCS(=O)(=O)C1
Answer: b. CCc1nc(C)cn1S(=O)(=O)c1cc([N+](=O)[O-])ccc1Cl
