Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.043\% 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] O=C(NCCCn1ccnc1)c1ccc(NS(=O)(=O)c2ccc(Cl)c(Cl)c2)cc1
[b] COc1ccc(C2=NN(C(=O)CCC(=O)O)C(c3ccc(Br)cc3)C2)cc1
Answer: a. O=C(NCCCn1ccnc1)c1ccc(NS(=O)(=O)c2ccc(Cl)c(Cl)c2)cc1
