Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.342\% 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(-c2nnc(COc3ccc4ccccc4c3)o2)cc(OC)c1OC
b. CCOc1ccc(N2C(=O)c3ccc(C(=O)OCc4c(C)noc4C)cc3C2=O)cc1
Answer: a. COc1cc(-c2nnc(COc3ccc4ccccc4c3)o2)cc(OC)c1OC
