Task: Answer the multiple choice question.
Question: Which compound exhibits a 20.087% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] CCOC(=O)c1c(C)[nH]c(C(=O)COC(=O)/C=C/c2ccc(OCC#N)c(OC)c2)c1C
[b] O=C(NCc1ccccn1)c1cc2c(ccc3ccccc32)oc1=O
Answer: b. O=C(NCc1ccccn1)c1cc2c(ccc3ccccc32)oc1=O
