Answer 2

Answer:

In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection.[1] It is one of the fundamental operations through which sets can be combined and related to each other. A nullary union refers to a union of zero ({\displaystyle 0}{\displaystyle 0}) sets and it is by definition equal to the empty set.
