Task: Answer the multiple choice question.
Question: Which drug has a 10.189\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CNCc1ccccc1OCc1ccccc1F.Cl
[b] Cc1cc(=O)[nH]c(SCC(=O)c2ccccc2)c1C#N
[c] O=C(C1COc2ccccc2O1)N1CCN(c2ccccc2F)CC1
[d] CCNc1ccc(C(=O)OC(C(=O)NC(N)=O)C(C)C)cc1[N+](=O)[O-]
Answer: c. O=C(C1COc2ccccc2O1)N1CCN(c2ccccc2F)CC1
