Task: Answer the multiple-choice question.
Query: Which compound exhibits a 17.055\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CCOC(=O)Cn1c(=NC(=O)c2cc(-c3cccs3)nc3ccccc23)sc2cc(S(N)(=O)=O)ccc21
b) O=c1c2ccccc2nc(/C=C/c2ccc(Br)cc2)n1CCCO
Answer: a. CCOC(=O)Cn1c(=NC(=O)c2cc(-c3cccs3)nc3ccccc23)sc2cc(S(N)(=O)=O)ccc21
