Assertion: Insects contribute the maximum to the total diversity of animals.
Reason: Angiosperms and insects are coevolved to perform as plant-pollinator.

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, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states that "Insects contribute the maximum to the total diversity of animals."
- Insects belong to the phylum Arthropoda, which is the largest phylum in the animal kingdom.
- Insects make up a significant portion of the total animal diversity, with estimates suggesting that they account for about 70% of all described animal species.

### Step 2: Understand the Reason
The reason states that "Angiosperms and insects are co-evolved to perform as plant-pollinator."
- Angiosperms (flowering plants) and insects have indeed co-evolved.
- Many insects, such as bees and butterflies, are essential for the pollination of angiosperms, which in turn provides food resources for these insects.
- This mutual relationship is a classic example of co-evolution, where both groups have adapted to benefit from each other.

### Step 3: Evaluate the Relationship Between Assertion and Reason
- Both the assertion and the reason are correct.
- The assertion is supported by the fact that insects are the most diverse group of animals, while the reason explains one of the significant ecological roles that insects play, which is pollination of angiosperms.

### Conclusion
Since both the assertion and reason are correct, and the reason correctly explains the assertion, the answer to the question is that both statements are true and the reason supports the assertion.

### Final Answer
Both the assertion and reason are correct, and the reason correctly explains the assertion.
