Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.982\% 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: O=C(Cn1c(CN2CCCCC2)nc2ccccc2c1=O)NCc1ccco1
b: CC(=O)Oc1ccc(-c2cc3ccc(OC(C)=O)cc3oc2=O)cc1
Answer: b. CC(=O)Oc1ccc(-c2cc3ccc(OC(C)=O)cc3oc2=O)cc1
