Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.471\% 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(Cn1c(=O)cnc2ccccc21)N1CCN(S(=O)(=O)c2cccc([N+](=O)[O-])c2)CC1
b Cc1ncc(SCc2ccccc2C)c(C)n1
c COc1ccc(OC)c(C2CC(=O)OC3=C2C(=O)CC(C)(C)C3)c1
d CCOC(=O)N1CCN(S(=O)(=O)c2ccc(F)c(C(=O)Nc3ccc(C(C)C)cc3)c2)CC1
e CCOC(=O)N1CCN(CC(=O)Nc2cc(OCC)ccc2OCC)CC1.Cl
Answer: c. COc1ccc(OC)c(C2CC(=O)OC3=C2C(=O)CC(C)(C)C3)c1
