Task: Answer the multiple choice question.
Question: Which compound has a 14.713\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C1C(Cl)=C(N2CCCC2)C(=O)N1c1ccccc1F
b O=c1cc(CNc2cc(C(F)(F)F)cc(C(F)(F)F)c2)nc2sccn12
Answer: a. O=C1C(Cl)=C(N2CCCC2)C(=O)N1c1ccccc1F
