Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -54.403\% 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] COc1ccccc1N1CC(C(=O)Nc2nnc(SCC(=O)NC(C)C)s2)CC1=O
[b] O=C(NCCNC(=O)c1ccc(-c2ccc(Cl)c(Cl)c2)o1)c1cnccn1
Answer: b. O=C(NCCNC(=O)c1ccc(-c2ccc(Cl)c(Cl)c2)o1)c1cnccn1
