Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 8.349\% 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) CCOC(=O)C1=C(CC)OC(N)=C(C#N)C1c1cc(OC)ccc1OC
(b) CNC(=O)Cc1nc2ccccc2n1CC(=O)Nc1cc(C)cc(C)c1
Answer: a. CCOC(=O)C1=C(CC)OC(N)=C(C#N)C1c1cc(OC)ccc1OC
