Problem statement: Answer the multiple-choice question.
Query: Which drug has a 3.355\% human ether-à-go-go related gene (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] C/C(CC(=O)Nc1ccccn1)=N\NC(=O)c1ccccc1
[b] CC(=O)N1CCN(C(=S)c2cccc([N+](=O)[O-])c2)CC1
[c] CC1=NN(c2nc(C)cc(C)n2)C(=O)C1CCC(C)C
[d] CC1CCN(c2ccc(NC(=O)C3CCCN3S(=O)(=O)c3ccc(F)cc3)cc2)CC1
Answer: c. CC1=NN(c2nc(C)cc(C)n2)C(=O)C1CCC(C)C
