Task: Answer the multiple-choice question.
Question: Which compound has a -10.276% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCC(=O)N/C(N)=N/c1nc2ccccc2o1
(b) COC(=O)c1ccc(OC(=O)c2ccc(OC)c(OC)c2)c(OC)c1
Answer: a. CCC(=O)N/C(N)=N/c1nc2ccccc2o1
