Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.320\% 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) COc1cc2nc3occc3c(OC)c2cc1OC
b) O=C(c1ccc(C(F)(F)F)cc1)N1CCC(=O)N(C(COCc2ccccc2)Cc2ccccc2)CC1
c) O=C(COC(=O)c1cc(=O)[nH]c(=O)[nH]1)Nc1cccc(S(=O)(=O)N2CCOCC2)c1
d) O=C(c1ccc(Cl)c([N+](=O)[O-])c1)N1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1
Answer: d. O=C(c1ccc(Cl)c([N+](=O)[O-])c1)N1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1
