Task: Answer the multiple-choice question.
Query: Which compound has a 4.744\% 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 N#CCCn1cc(C=O)c(-c2cccs2)n1
c Cc1cccc(CC(=O)N2CCN=C2SCc2ccc([N+](=O)[O-])cc2)c1
d Cc1ccc(SCC(=O)OCC(=O)NCc2ccco2)cc1
e COc1ccc(S(=O)(=O)NN(C)C)cc1N(C)S(=O)(=O)c1ccc(Cl)cc1
Answer: b. N#CCCn1cc(C=O)c(-c2cccs2)n1
