Task: Answer the multiple choice question.
Question: Which compound has a 16.410\% human ether-à-go-go related gene (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) C=CCNc1nc(Nc2cc(Cl)ccc2OC)nc(OC)n1
b) Cn1c(O)c(C2=NNC(c3ccc(Cl)cc3)C2)c(=O)n(C)c1=O
Answer: a. C=CCNc1nc(Nc2cc(Cl)ccc2OC)nc(OC)n1
