Task: Answer the multiple-choice question.
Question: Which compound exhibits a 18.824\% 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] CN(C)S(=O)(=O)Nc1cc(F)cc(F)c1
[b] O=C(NCc1cccnc1)c1ccccc1Br
[c] O=C(CCN1C(=O)C2C3C=CC(C3)C2C1=O)Nc1ccc2ncccc2c1
Answer: c. O=C(CCN1C(=O)C2C3C=CC(C3)C2C1=O)Nc1ccc2ncccc2c1
