Task: Answer the multiple-choice question.
Question: Which compound has a -18.277\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] Cc1nc(/C=C/c2ccccc2)cc(/C=C/c2ccccc2)n1
[b] CCCCn1c(O)c(C(C)=NCc2cc(OC)cc(OC)c2)c(=O)[nH]c1=O
[c] O=C(NCc1cccs1)c1ccc2c(c1)OCCO2
Answer: b. CCCCn1c(O)c(C(C)=NCc2cc(OC)cc(OC)c2)c(=O)[nH]c1=O
