Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.857\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CC1=NNC(=O)C1CCC(=O)N/N=C\c1ccccc1[N+](=O)[O-]
[b] N#CC(C#N)=NNc1ccc(S(=O)(=O)N2CCCC2)cc1
[c] CN(C)NC(=S)NC1CC2CCC1C2
[d] CC1CC(=O)Nc2ccccc2S1(=O)=O
Answer: c. CN(C)NC(=S)NC1CC2CCC1C2
