Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.138\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] N#C/C(=N\Nc1ccc(S(=O)(=O)N2CCOCC2)cc1)C(N)=S
[b] COc1ccc(C(C)=O)c(Oc2nc(CN3CCOCC3)nc3scc(-c4cccs4)c23)c1
Answer: b. COc1ccc(C(C)=O)c(Oc2nc(CN3CCOCC3)nc3scc(-c4cccs4)c23)c1
