    Some authors use "⊂" for subset .. and "⊆" for "proper subset" .. and some take the other way round. Which way have you learnt it @ethompsonn ?

    Here are some important properties fo sets : • Null set is a subset of every set. • Every set is a subset of itself. Thus, this makes the first and the second option correct. And, you're left with just the 3rd option. So, That's the false statement.
