Task: Answer the multiple-choice question.
Question: Which compound has a -3.518% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) CC1=NN(c2ccccc2)C(=O)C1N=Nc1cccc(O)c1
b) CCOC(=O)c1sc2nc(C)c([N+](=O)[O-])c(COC)c2c1N
c) Cc1cccc(Nc2nc(N)c([N+](=O)[O-])c(N3CCOCC3)n2)c1
d) O=C(N/N=C/c1ccc([N+](=O)[O-])cc1)c1cccs1
e) COc1ccccc1N(C)C(=O)c1cc(S(=O)(=O)N2CCCC2)cn1C
Answer: b. CCOC(=O)c1sc2nc(C)c([N+](=O)[O-])c(COC)c2c1N
