Task: Answer the multiple choice question.
Query: Which drug has a -0.507\% 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 additional words.
Options:
[a] CCOc1ccc(S(=O)(=O)N2CCN(C(=O)c3cc(-c4ccccc4)nn3-c3ccccc3)CC2)cc1
[b] O=C(CCC(=O)N1CCOc2ccccc21)NCCCc1ccccc1
Answer: b. O=C(CCC(=O)N1CCOc2ccccc21)NCCCc1ccccc1
