Task: Answer the multiple choice question.
Question: Which compound exhibits a 14.700\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(N=Nc1c(O)n(Cc2ccccc2)c2ccccc12)c1cc2ccccc2cc1O
b) CCN1CCN(C(=O)c2ccccc2NC(=O)c2ccc(Cl)cc2)CC1
Answer: a. O=C(N=Nc1c(O)n(Cc2ccccc2)c2ccccc12)c1cc2ccccc2cc1O
