Problem statement: Answer the multiple choice question.
Question: Which compound has a -7.212\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) CCOC(=O)C(CC)/C(C)=N/NC(=O)c1ccccc1[N+](=O)[O-]
b.) CC(=O)c1ccc(S(=O)(=O)Nc2cccc(-c3cn4c(n3)SCC4)c2)cc1
c.) CCCc1nc(SCC(=O)Nc2ccc(N3CCOCC3)cc2)c2ccccc2n1
Answer: a. CCOC(=O)C(CC)/C(C)=N/NC(=O)c1ccccc1[N+](=O)[O-]
