The correct option is (c).
Explanation
Tropical Deciduous Forests represent the most extensive natural vegetation type in India, closely associated with the tropical monsoon climate.
- Statement 1 is Correct: These forests are the most widespread forests in India, covering the largest percentage of the country's total forest cover.
- Statement 2 is Correct: They are popularly known as monsoon forests because their distribution and characteristics are heavily influenced by the seasonal monsoon rainfall pattern.
- Statement 3 is Correct: These forests spread over regions receiving annual rainfall between 70 cm and 200 cm. Based on the availability of water, they are further divided into Moist Deciduous (100–200 cm) and Dry Deciduous (70–100 cm).
- Statement 4 is Incorrect: The term "deciduous" implies the shedding of leaves. Trees in these forests shed their leaves for about six to eight weeks during the dry summer season to prevent loss of moisture through transpiration. It is the Tropical Evergreen forests that do not shed their leaves simultaneously.
Key Takeaway: Tropical Deciduous Forests (Monsoon Forests) are the dominant vegetation type in India, thriving in rainfall zones of 70–200 cm, and are characterized by distinct seasonal leaf shedding.
