Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.723\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. COc1ccc(OCC(=O)Nc2ccc(S(=O)(=O)Nc3cc(C)nc(C)n3)cc2)cc1
b. Cc1cc(C)c(C)c(C(=O)CSc2nnc(-c3ccc4[nH]c(C)c(C)c4c3)o2)c1C
c. COc1cc(NS(=O)(=O)c2ccc(NC(=O)COc3ccc(C)cc3C)cc2)nc(OC)n1
d. O=C1CSCC(=O)N1c1ccccc1
e. O=C(C(=C1N(Cc2ccc(Cl)nc2)CCN1Cc1ccc(Cl)nc1)[N+](=O)[O-])C(Cl)Cl
Answer: e. O=C(C(=C1N(Cc2ccc(Cl)nc2)CCN1Cc1ccc(Cl)nc1)[N+](=O)[O-])C(Cl)Cl
