Task: Answer the multiple-choice question.
Question: Which drug exhibits a -44.960\% 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] O=C(NCCOc1ccccc1)C1CCC(=O)N(CCc2ccc(Cl)cc2)C1
[b] Cc1noc(C)c1N=Nc1ccc(Br)cc1C(=O)O
Answer: a. O=C(NCCOc1ccccc1)C1CCC(=O)N(CCc2ccc(Cl)cc2)C1
