Problem statement: Answer the multiple choice question.
Question: Which drug has a 21.801\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCOC(=O)c1c(-c2ccccc2)oc2ccc(OC(C)=O)cc12
b: O=C1NC(=Nc2ccccc2)S/C1=C\C=C\c1ccco1
Answer: a. CCOC(=O)c1c(-c2ccccc2)oc2ccc(OC(C)=O)cc12
