Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.814\% 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: COC(=O)c1cccc(NC(=O)Nc2ccc(Cl)c(Cl)c2)c1
b: CCN(CC)c1ccc(/C=N/NC(=S)NC)c(O)c1
c: O=c1cc(NC2CCCCCC2)[nH]c(=O)[nH]1
Answer: b. CCN(CC)c1ccc(/C=N/NC(=S)NC)c(O)c1
