Task: Answer the multiple choice question.
Query: Which compound exhibits a 13.989\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) Cc1ccc(S(=O)(=O)CCc2nnc(NC(=O)c3cnccn3)s2)cc1
b) O=C(CSc1nc2ccccc2s1)N/N=C/c1cc([N+](=O)[O-])ccc1O
c) COc1ccccc1Nc1nc(C2(C)CCC(=O)O2)cs1
d) O=C(COC(=O)c1ccco1)c1ccc2ccccc2c1
e) CC(=O)Nc1ccc(S(=O)(=O)N2CCOCC2)cc1
Answer: b. O=C(CSc1nc2ccccc2s1)N/N=C/c1cc([N+](=O)[O-])ccc1O
