Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.045\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CC(=O)Nc1ccc(C2(c3ccc(NC(C)=O)cc3)C(=O)Nc3ccccc32)cc1
[b] O=C(NC(Cc1c[nH]c2ccccc12)C(=O)N/N=C/c1ccc(Cl)cc1)c1cccs1
[c] CCOC(=O)C1CCN(c2c(N3CCCCCC3)c(=O)c2=O)CC1
Answer: c. CCOC(=O)C1CCN(c2c(N3CCCCCC3)c(=O)c2=O)CC1
