Task: Answer the multiple choice question.
Question: Which compound exhibits a -0.606\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1cccc(-c2nn(-c3ccccc3)cc2C(=O)O)c1
b CCCOC(=O)Nc1ccccc1C(N)=O
c CCOC(=O)C(=N/O)/C(C)=N/NC(=O)C(=O)Nc1cc(Cl)ccc1Cl
d O=C(Oc1ccc2[nH]cc(CCN3C(=O)c4ccccc4C3=O)c2c1)c1ccco1
Answer: b. CCCOC(=O)Nc1ccccc1C(N)=O
