Task: Answer the multiple-choice question.
Query: Which compound has a 17.820\% 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, or d without using any other words.
Options:
a. COc1cc(CNC2CCCc3ccccc32)cc(OC)c1OC.O=C(O)C(=O)O
b. Cc1cccc(S(=O)(=O)Nc2nc3ccccc3nc2NCc2ccco2)c1
c. O=C(NCC(F)(F)F)Nc1ccccn1
d. N=C1C(c2nc3ccccc3s2)=C(O)CN1NC(=O)c1ccccc1[N+](=O)[O-]
Answer: d. N=C1C(c2nc3ccccc3s2)=C(O)CN1NC(=O)c1ccccc1[N+](=O)[O-]
