Task: Answer the multiple-choice question.
Question: Which drug exhibits a 11.739\% 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: CCOc1cc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2CCc2ccccc2)ccc1O
b: COC(=O)C1(C)Cc2cc(OC(C)=O)c(OC(C)=O)cc2N1
Answer: b. COC(=O)C1(C)Cc2cc(OC(C)=O)c(OC(C)=O)cc2N1
