Assertion`:-` Bacteria are very complex in bahaviour.
Reason`:-` Bacteria are unicellular prokaryotes

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertiion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False

Explanation

To analyze the assertion and reason provided in the question, we can break down the steps as follows:

### Step 1: Understand the Assertion
The assertion states that "Bacteria are very complex in behavior." This suggests that despite being simple organisms, bacteria exhibit a range of complex behaviors, such as communication, movement, and adaptation to environments.

**Hint:** Consider the various functions and interactions bacteria can have in different environments.

### Step 2: Understand the Reason
The reason states that "Bacteria are unicellular prokaryotes." This means that bacteria consist of a single cell and lack a well-defined nucleus, categorizing them as prokaryotic organisms.

**Hint:** Recall the characteristics of prokaryotic cells and how they differ from eukaryotic cells.

### Step 3: Analyze the Relationship
Now, we need to analyze the relationship between the assertion and the reason. While both statements are true, the reason does not provide a valid explanation for the assertion. The complexity of bacterial behavior is not solely due to their unicellular and prokaryotic nature; rather, it stems from their biochemical processes and interactions.

**Hint:** Think about how complexity can arise in simple organisms through their interactions and adaptations.

### Step 4: Conclusion
Based on the analysis:
- Both the assertion and reason are true.
- However, the reason does not explain the assertion adequately.

Thus, the correct conclusion is that both the assertion and reason are true, but the reason is not a correct explanation of the assertion.

**Final Answer:** Both assertion and reason are true, but reason is not a correct explanation of assertion.
