1.	If B is a null set and A is some set then which one of the following is false?(a) B⊆A(b) B∪A=A(c) B∩A=A(d) B∩A=BThis question was posed to me by my college professor while I was bunking the class.This is a very interesting question from The Empty Set topic in portion Sets of Mathematics – Class 11
Answer» The correct answer is (C) B∩A=A To ELABORATE: An empty set is a subset of every set, also the union of a set with an empty set gives the set itself, SINCE, there are no elements in an empty set hence INTERSECTION with an empty set gives empty set.
