Task: Answer the multiple choice question.
Query: Which drug has a 3.487\% 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 other words.
Options:
a CN1CCN(C(=O)C2=C[C@H](c3coc4ccccc4c3=O)C[C@H](OCc3ccc(CO)cc3)O2)CC1
b COC(=O)c1ccc(-n2c(C)cc(C(=O)CSc3cccc[n+]3[O-])c2C)cc1
Answer: a. CN1CCN(C(=O)C2=C[C@H](c3coc4ccccc4c3=O)C[C@H](OCc3ccc(CO)cc3)O2)CC1
