In a Venn diagram, what does the rectangle usually represent?
Answer and explanation
Correct answer: Universal set U
In the standard representation of a Venn diagram, the outer rectangle denotes the universal set U. It provides the complete context or collection of objects under discussion. Circles or other closed curves drawn inside the rectangle represent particular sets such as A and B. The empty set is represented by no enclosed region, while A ∩ B is only the overlapping part of two circles. Therefore the rectangle represents U, making option A correct.
