Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -2.905\% 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 additional words.
Options:
(a) O=C(NNS(=O)(=O)c1cc(Cl)cc(Cl)c1)c1sccc1-n1cccc1
(b) O=S(=O)(NCCCN1CCOCC1)c1ccc(Cl)s1
(c) COc1ccc(CCNS(=O)(=O)c2ccc(Cl)cc2)cc1OC
(d) O=C(Nc1ccc(Oc2cccnc2)cc1)c1ccc([N+](=O)[O-])cc1
Answer: d. O=C(Nc1ccc(Oc2cccnc2)cc1)c1ccc([N+](=O)[O-])cc1
