Bella is older than Charlie and younger than Lily. Teddy is older than Bella. Which two people could be the same age?  Looking at the first sentence, Bella is older than Charlie and younger than Lily, we get this inequality for their ages.  And then looking at the second one, that Teddy is older than Bella, we get this one. And now, since we've lined everything up at Bella and all of  our inequalities are going the same way, we see that Lily and Teddy could possibly be the same age. That means our answer is B.
