Problem statement: Answer the MCQ question.
Question: Which compound has a 4.949\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] C/C(N)=C(/C#N)C(=O)COC(=O)COc1ccc(Cl)cc1C
[b] O=C(O)C1CC(c2cccc(Br)c2)=NO1
[c] Cc1cccc(OCCNc2nc3c(c(=O)n(C)c(=O)n3C)n2C)c1
[d] O=C(COc1ccc([N+](=O)[O-])cc1)Nc1ccc(CN2CCOCC2)cc1
Answer: a. C/C(N)=C(/C#N)C(=O)COC(=O)COc1ccc(Cl)cc1C
