Task: Answer the multiple choice question.
Query: Which compound has a 4.230% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(Cn1nnc(-c2ccccc2Cl)n1)N/N=C/c1ccc(-c2cccc(Cl)c2)o1
b: CCC1CCCCN1C(=O)NC(=O)c1ccccc1
c: COc1ccc2[nH]c(=O)c(CN(Cc3ccccc3)C(=S)NCC3CCCO3)cc2c1
d: O=[N+]([O-])c1cn(Cc2ccccc2)cn1
e: O=C(c1ccc(Cl)c(Cl)c1)N1CCC(=O)N(C(COCc2ccc(Cl)cc2)Cc2ccccc2)CC1
Answer: d. O=[N+]([O-])c1cn(Cc2ccccc2)cn1
