Task: Answer the MCQ question.
Question: Which compound exhibits a 9.199\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCOCCCNC(=O)/C(C#N)=C/c1cc(OC)c(O)c([N+](=O)[O-])c1
b: CCCCOC(=O)c1ccc(NC(=O)Nc2ccc(OC)c(OC)c2)cc1
Answer: a. CCOCCCNC(=O)/C(C#N)=C/c1cc(OC)c(O)c([N+](=O)[O-])c1
