Task: Answer the multiple-choice question.
Query: Which compound has a -7.780\% 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 additional words.
Options:
[a] c1ccc(-c2[nH]ncc2CN2CCc3ccccc3C2)cc1
[b] Nc1c(-c2ccccc2Cl)cnn1-c1cccc([N+](=O)[O-])c1
[c] O=C(NCC(=O)N1CCCC1)c1ccccc1F
[d] CCCN(CC(=O)Nc1ccccc1OC)C(=O)Cn1[nH]c(=O)c2ccccc2c1=O
[e] CC(=O)Nc1ccc(S(=O)(=O)NCCc2csc(-c3cccnc3)n2)cc1
Answer: b. Nc1c(-c2ccccc2Cl)cnn1-c1cccc([N+](=O)[O-])c1
