Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.946\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CN1C(=O)/C(=C/c2ccccc2OCc2cccc(F)c2)N(C)C1=S
b.) O=C(Oc1cc(Cl)ccc1Cl)c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
Answer: a. CN1C(=O)/C(=C/c2ccccc2OCc2cccc(F)c2)N(C)C1=S
