Task: Answer the multiple-choice question.
Question: Which drug exhibits a 21.943\% 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 COc1cc(OC)cc(C(=O)NNC(=O)C(=O)Nc2cc(OC)c(Cl)cc2OC)c1
b Cc1cc(Cl)c(S(=O)(=O)N2CCCC2)cc1OCC(N)=O
Answer: a. COc1cc(OC)cc(C(=O)NNC(=O)C(=O)Nc2cc(OC)c(Cl)cc2OC)c1
