Task: Answer the MCQ question.
Question: Which drug has a 3.412\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCc1ccc(C2=NN(S(C)(=O)=O)C(c3cccs3)C2)cc1
b: CC(C)(C)C#CC(CCc1ccccc1)OS(N)(=O)=O
c: CCOc1ccc(NC(=O)c2ccc(NCC(=O)N3CCCCCC3)cc2)cc1
d: CCOC(=O)COc1cc(C)nc2nc(-c3ccccc3)cn12
e: COc1cc(NC(=O)Nc2cccc([N+](=O)[O-])c2)cc(OC)c1
Answer: a. CCc1ccc(C2=NN(S(C)(=O)=O)C(c3cccs3)C2)cc1
