Task: Answer the multiple choice question.
Question: Which compound has a -12.954% 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 additional words.
Options:
a. O=C(COc1ccc(Cl)cc1)NC1=NN(c2ccccc2)C(=O)C1
b. O=C(N/N=C/C=C/c1ccc([N+](=O)[O-])cc1)c1cccs1
c. CN(Cc1ccccc1)C(=O)c1cc(S(=O)(=O)N2CCOCC2)cn1C
d. CC1Cc2ccccc2N1CC(=O)NC(=O)NC(C)(C)C
e. O=C1CCCN1CCC1CCN(C2CC(=O)N(Cc3ccc(N4CCCC4=O)cc3)C2=O)CC1
Answer: b. O=C(N/N=C/C=C/c1ccc([N+](=O)[O-])cc1)c1cccs1
