Task: Answer the multiple choice question.
Question: Which compound has a -23.400\% 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 other words.
Options:
a NNC(=O)CCN(Cc1ccco1)S(=O)(=O)c1ccc(Cl)cc1
b NC(=O)C1CCN(c2nc(-c3ccccc3)nc3ccccc23)CC1
c CCOC(=O)CSc1nnc(-c2ccco2)n1-c1ccccc1
d COc1ccccc1N(CC1CO1)S(=O)(=O)c1ccccc1
Answer: b. NC(=O)C1CCN(c2nc(-c3ccccc3)nc3ccccc23)CC1
