Step 1: Understanding the Concept:
This historical question focuses on the origin of "Van Mahotsava" (the Forest Festival), which is celebrated annually across India to encourage tree planting and environmental awareness.
Step 2: Detailed Explanation:
Van Mahotsava was initiated in India in 1950 by Kanaiyalal Maneklal Munshi (K. M. Munshi).
At the time, Munshi served as the Union Minister for Food and Agriculture.
He envisioned the festival as a way to:
- Create public enthusiasm for tree planting and forest conservation.
- Increase tree cover to protect agricultural lands from erosion.
- Promote local food and fuel security.
The festival is celebrated during the first week of July (July 1st to July 7th), which coincides with the onset of the southwest monsoon in most parts of India, providing ideal moisture conditions for sapling survival.
Step 3: Final Answer:
Van Mahotsava was started for the first time by K. M. Munshi.
This corresponds to Option (D).
