Task: Answer the multiple choice question.
Question: Which compound exhibits a -3.589% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CN1CCN(S(=O)(=O)c2ccc3[nH]c(=O)oc3c2)CC1
b) O=[N+]([O-])c1ccc(N=Cc2ccc(Br)c([N+](=O)[O-])c2)cc1
c) CCOCCCN(C)C1CCN(C(=O)c2oc3ccccc3c2NC(=O)Cc2ccc(F)cc2)CC1
d) Cc1ccnc(NC(=O)CCC(=O)N(CC(=O)NCCc2ccccc2)c2ccc(F)cc2)c1
Answer: b. O=[N+]([O-])c1ccc(N=Cc2ccc(Br)c([N+](=O)[O-])c2)cc1
