Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.537\% 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] CS(=O)(=O)Nc1ccccc1C(=O)c1ccccc1
[b] CCN(CC)S(=O)(=O)c1ccc(Br)c(OC)c1
[c] CCOC(=O)C1=C(C)Nc2nc3ccccc3n2C1c1cccs1
Answer: c. CCOC(=O)C1=C(C)Nc2nc3ccccc3n2C1c1cccs1
