The correct Answer is:
To solve the question regarding the assertion and reason about cyanobacteria, let's break it down step by step: ### Step 1: Analyze the Assertion - The assertion states that "Cyanobacteria are photosynthetic autotrophs." - Cyanobacteria are indeed capable of photosynthesis, meaning they can produce their own food using sunlight, carbon dioxide, and water. This makes the assertion true. ### Step 2: Analyze the Reason - The reason states that "Cyanobacteria have chlorophyll a and b similar to green plants." - While cyanobacteria do contain chlorophyll a, they do not have chlorophyll b. Instead, they have other pigments that assist in photosynthesis. Therefore, this statement is false. ### Step 3: Determine the Relationship - Since the assertion is true and the reason is false, we need to identify the correct option based on this analysis. ### Conclusion - The correct answer is option 3: "If assertion is true but reason is false." ---
