o its the middle one?

zepdrix · Answer

Both of them contain the set E?
No.

Look at the diagram I drew, clearly D does not have E inside of it.

zepdrix · Answer

D is a subset of E,
so D is contained within E.

E has D inside of it.
And D has D inside of itself, nothing special there.

So we can see that they both contain all of D, yes?
