Task: Answer the multiple choice question.
Question: Which compound has a -1.985\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] Cc1ccc(NCC(=O)N/N=C\c2ccc([N+](=O)[O-])o2)cc1
[b] O=C1C=C(O)c2c(O)cccc2C1=O
Answer: a. Cc1ccc(NCC(=O)N/N=C\c2ccc([N+](=O)[O-])o2)cc1
