Task: Answer the multiple choice question.
Question: Which drug has a 12.798\% 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 CCOC(=O)[C@H]1[C@H]2COc3ccc(OC)cc3[C@@H]2N2C(=O)c3ccccc3NC(=O)[C@@]12C
b CCOC(=O)c1ccc(N2C=C(C(=O)OC)C(c3ccc(OC)c(O)c3)C(C(=O)OC)=C2)cc1
Answer: b. CCOC(=O)c1ccc(N2C=C(C(=O)OC)C(c3ccc(OC)c(O)c3)C(C(=O)OC)=C2)cc1
