Task: Answer the multiple-choice question.
Question: Which compound exhibits a 15.070\% 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] O=C(NCc1cccs1)NC1CCCCC1
[b] CCN(CC)c1nc2c(c(=O)[nH]c(=O)n2C)n1CCCc1ccccc1
[c] CCOC(=O)C(C)c1nc2ccccc2[nH]c1=O
Answer: c. CCOC(=O)C(C)c1nc2ccccc2[nH]c1=O
