Task: Answer the multiple choice question.
Query: Which compound exhibits a 10.501\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a CCC(=O)Nc1ccc(Nc2nc(C)c([N+](=O)[O-])c(Nc3ccc(NC(=O)CC)cc3)n2)cc1
b Cc1cc(C)c2c(CN3CCCCC3)cc(=O)oc2c1
Answer: a. CCC(=O)Nc1ccc(Nc2nc(C)c([N+](=O)[O-])c(Nc3ccc(NC(=O)CC)cc3)n2)cc1
