Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.545\% 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 COC(=O)c1scc(S(C)(=O)=O)c1-n1cccc1
b COc1cccc(-c2noc(C3CCCN(S(=O)(=O)c4cccc(Cl)c4C)C3)n2)c1
Answer: b. COc1cccc(-c2noc(C3CCCN(S(=O)(=O)c4cccc(Cl)c4C)C3)n2)c1
