Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.734\% 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) C=CCn1cccc(C(=O)Nc2cc(OC)ccc2OC)c1=O
(b) CCn1c(COc2ccccc2C(N)=O)nc2ccccc21
Answer: a. C=CCn1cccc(C(=O)Nc2cc(OC)ccc2OC)c1=O
