Task: Answer the multiple choice question.
Query: Which compound has a 5.013\% 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] CCOC(=O)C1=C(O)C(=O)NC(c2ccccc2)=C(OCC)C1
[b] CC(C)c1ccc(NS(=O)(=O)c2ccc3c(c2)oc(=O)n3C)cc1
[c] COc1ccccc1-n1nnnc1SCC(=O)Nc1ccc(C)c(N)c1
Answer: a. CCOC(=O)C1=C(O)C(=O)NC(c2ccccc2)=C(OCC)C1
