In Venn diagram questions: • The centre intersection represents elements common to all sets.

Answer 1

The Correct Option is A

Concept:
The region common to rectangle (wheat), square (gram), circle (maize), and triangle (rice) represents cultivation of all four commodities.
Step 1: Identify intersection of all four shapes.
Step 2: Find the number written in that common region. From the diagram the common overlapping region is: \[ 7 \]
Step 3: Conclusion \[ \therefore \text{Area cultivated by all four commodities = 7} \]
