Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.540\% 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 CCOC(=O)C1CCCCC12C(C#N)=C(N)Oc1n[nH]c(C)c12
b CCOc1ccc(N2C(=O)CC(n3nc(C)cc3C)C2=O)cc1
Answer: a. CCOC(=O)C1CCCCC12C(C#N)=C(N)Oc1n[nH]c(C)c12
