Problem statement: Answer the multiple choice question.
Question: Which compound has a 2.231\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(Cc2nnc(CCc3ccccc3)s2)cc1
b: CCOC(=O)c1c(C)[nH]c(=S)c(C#N)c1-c1ccccc1
c: Cc1ccc(/C=N/NC(=O)c2cccs2)cc1[N+](=O)[O-]
Answer: c. Cc1ccc(/C=N/NC(=O)c2cccs2)cc1[N+](=O)[O-]
