Task: Answer the MCQ question.
Query: Which compound exhibits a 5.785\% 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(OCC(=O)N/N=c2\oc3c(OC)cccc3cc2C(N)=O)cc1
[b] CCOC(=O)CSC1=C(C#N)C(c2ccccc2OCC)C(C(=O)OCC)C(=O)N1
Answer: a. COc1ccc(OCC(=O)N/N=c2\oc3c(OC)cccc3cc2C(N)=O)cc1
