Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 6.819\% hERG inhibition at a concentration of 1uM?
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(Nc1ccccc1N1CCOCC1)c1ccc([N+](=O)[O-])cc1
b) COc1cccc2cc(C(=O)NCc3ccco3)c(=Nc3ccc(C(=O)O)cc3)oc12
c) CCOC(=O)COc1ccc(/C=C2/SC(=Nc3ccccc3)N(Cc3cccnc3)C2=O)cc1OC
d) COc1ccc(C)cc1NC(=S)N1CCN(c2ccccn2)CC1
e) CCCCCNc1nc2sc3c(c2c(=O)n1-c1cccc(Cl)c1)CCN(C)C3
Answer: a. O=C(Nc1ccccc1N1CCOCC1)c1ccc([N+](=O)[O-])cc1
