Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.976\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) Cc1onc(C(=O)NCCc2ccccc2)c1[N+](=O)[O-]
(b) COc1cc(/C=C(\C#N)c2nc3ccccc3[nH]2)cc(OC)c1O
(c) CCOC(=O)Nc1sc2c(c1C#N)CCCC2
Answer: b. COc1cc(/C=C(\C#N)c2nc3ccccc3[nH]2)cc(OC)c1O
