At the 64th National Film Awards, which film received the award for Best Environment Film including agricultural film?

Introduction / Context:
This question is about the 64th National Film Awards and focuses on the category of Best Environment Film, including agricultural film, in the non feature section. You are required to identify which film received this specific award. National Film Awards frequently appear in current affairs and static GK sections of competitive exams.

Given Data / Assumptions:

• The edition is the 64th National Film Awards.
• The category is Best Environment Film including agricultural film, in the non feature segment.
• The options include Kaasav, Dashkriya, Ventilator, The Tiger Who Crossed the Line, and Loktak Lairembee.

Concept / Approach:
The correct approach is to distinguish between feature films and non feature films and to recall which film was awarded specifically as Best Environment Film in the non feature category at the 64th National Film Awards. The documentary The Tiger Who Crossed the Line, directed by Krishnendu Bose, received the National Award for Best Environment Film including agricultural film at that edition. Other listed films won different awards or belong to the feature film category.

Step-by-Step Solution:
Step 1: Recall that Kaasav is a Marathi feature film that won the award for Best Feature Film at the 64th National Film Awards.Step 2: Note that Dashkriya and Ventilator are also feature films which received other recognitions, such as awards for direction or regional best film.Step 3: Recognise that The Tiger Who Crossed the Line is a documentary dealing with issues related to tigers and human animal conflict, placed in the non feature section.Step 4: Recall that this documentary was explicitly cited as the Best Environment Film including agricultural film at the 64th National Film Awards.Step 5: Loktak Lairembee is a feature film that received the award for Best Film on Environment Conservation or Preservation, which is a different category, so it is not the answer for Best Environment Film including agricultural film.Step 6: Therefore, The Tiger Who Crossed the Line is the correct choice.

Why Other Options Are Wrong:

• Kaasav: Winner of the Best Feature Film award at the same National Film Awards, but not the Best Environment Film in the non feature category.
• Dashkriya: A Marathi feature film honoured in a different category, not for Best Environment Film including agricultural film.
• Ventilator: A Marathi feature film that received awards for direction and other categories, but not the environment film award.
• Loktak Lairembee: A Manipuri feature film that won the award for Best Film on Environment Conservation or Preservation, which is a separate category from Best Environment Film including agricultural film.

Common Pitfalls:
Candidates often confuse similar sounding award categories, such as Best Environment Film and Best Film on Environment Conservation, or mix up feature and non feature sections. Another frequent mistake is to select Kaasav simply because it is the most famous winner from that year. Careful reading of the exact category name and distinguishing between documentary and feature films is essential.

Final Answer:
The Tiger Who Crossed the Line received the award for Best Environment Film including agricultural film at the 64th National Film Awards, so option D is correct.
