Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.310\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CCOc1ccc(NC(=O)CSc2nc3[nH]ncc3c(=O)n2-c2ccccc2OC)cc1
b) CCN(Cc1cnn(C)c1)Cc1nc(Cc2ccccc2Cl)no1
c) O=c1c(-c2ccco2)[n+]([O-])c2ccccc2n1OCc1ccccc1F
d) O=C(NCc1cc([N+](=O)[O-])ccc1O)c1cccnc1Sc1ccc(Cl)cc1
Answer: d. O=C(NCc1cc([N+](=O)[O-])ccc1O)c1cccnc1Sc1ccc(Cl)cc1
