Task: Answer the multiple choice question.
Query: Which compound exhibits a 13.959\% 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: COc1ccc(C(=O)N[C@H](C(=O)Nc2ccc(S(=O)(=O)N3CCOCC3)cc2)C(C)C)cc1
b: CNC(=O)C(C#N)(Cc1cc(C(C)=O)ccc1OC)Cc1cc(C(C)=O)ccc1OC
Answer: b. CNC(=O)C(C#N)(Cc1cc(C(C)=O)ccc1OC)Cc1cc(C(C)=O)ccc1OC
