Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.077% 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: COC(=O)c1cn(NC(=O)COc2ccc(Cl)cc2)c(=O)c2ccccc12
b: COc1ccc(C(=O)CSc2nnc(-c3cnccn3)n2Cc2ccco2)cc1
c: COc1ccc(OC)c(C(C)NC=O)c1
d: O=C(CSc1nc2ccc([N+](=O)[O-])cc2[nH]1)c1ccc(Cl)cc1
Answer: d. O=C(CSc1nc2ccc([N+](=O)[O-])cc2[nH]1)c1ccc(Cl)cc1
