A: Holistic approach explains the environmental interactions.
R: All environmental factors are integrated with no limits of time and space

Options

A. If both Assertion and Reason are true and the reason is correct explanation of the assertion, then mark (1).
B. If both Assertion and Reason are true but the reason are true the reason is not the correct explanation of the assertion, then mark (2).
C. If Assertion is true but Reason is false, then mark (3).
D. If both Assertion and Reason are false, then mark (4).

Answer

To solve the question regarding the assertion and reason, we will analyze both statements step by step.

### Step 1: Understand the Assertion
- The assertion states: "Holistic approach explains the environmental interactions."
- A holistic approach in ecology means considering the entire ecosystem and how various components interact with each other. It emphasizes the interconnectedness of all living organisms and their environment.

### Step 2: Analyze the Reason
- The reason states: "All environmental factors are integrated with no limits of time and space."
- This suggests that environmental factors are interconnected without any constraints. However, in ecological studies, while many factors are interrelated, they can be influenced by specific time frames and spatial boundaries. Therefore, this statement is misleading.

### Step 3: Determine the Correctness of Each Statement
- The assertion is correct because a holistic approach does indeed explain environmental interactions by considering the whole ecosystem.
- The reason is incorrect because it overgeneralizes the integration of environmental factors without acknowledging the importance of time and space in ecological studies.

### Step 4: Conclusion
- Since the assertion is correct and the reason is incorrect, the correct answer to the question is that the assertion is true, but the reason is false.

### Final Answer
- Assertion (A) is true, and Reason (R) is false.
