Task: Answer the multiple-choice question.
Question: Which compound has a 4.542\% 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 O=C(Nc1ccccc1-c1ccccc1)c1ccc(=O)[nH]n1
b Cc1ccc(-n2nc(C)c(C(=O)Nc3cccc(C(=O)NC4CC4)c3)n2)c(C)c1
c CCC(=O)Nc1cccc(NC(=O)CSc2nc3c(c(=O)n(C)c(=O)n3C)n2C)c1
Answer: a. O=C(Nc1ccccc1-c1ccccc1)c1ccc(=O)[nH]n1
