To solve this question, we need to determine the number that lies in the intersection of the regions representing temples, parks, and theatre, excluding the beach in the Venn Diagram.

Let's analyze the given Venn Diagram step by step:

1. The circle represents the region of temples.
2. The square represents the area of parks.
3. The triangle represents the region of theatre.
4. The rectangle denotes the area of beach.

We are looking for the region that is common to temples, parks, and theatre but not part of the beach. In the diagram:

• The number 9 is in the intersection of all four areas, including the beach.
• The number 8 is in the intersection of the circle, square, and triangle, but not the rectangle.

Thus, the region representing temples, parks, and theatre, but excluding the beach, is 8.

Therefore, the correct answer is 8.
