Task: Answer the multiple choice question.
Question: Which compound exhibits a 24.167\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COC(=O)c1sccc1NN1C(=O)c2ccccc2C1=O
[b] O=C(N/C(=C/c1cn(-c2ccccc2)nc1-c1ccccc1)C(=O)N1CCOCC1)c1ccc(Cl)cc1Cl
[c] O=C(NNC(=O)c1cccnc1Cl)c1ccc(F)cc1
Answer: b. O=C(N/C(=C/c1cn(-c2ccccc2)nc1-c1ccccc1)C(=O)N1CCOCC1)c1ccc(Cl)cc1Cl
