The correct Answer is:
To determine the classification of the alga collected by the research scholar, we need to analyze the pigments present in the cells of the alga. The alga contains chlorophyll d and phycocyanin, which are key indicators of its classification. ### Step-by-Step Solution: 1. **Identify the pigments present**: The alga contains chlorophyll d and phycoerythrin. These pigments are crucial for determining the classification of the alga. 2. **Examine the options**: The options provided are: - Cyanophyceae (Blue-green algae) - Chlorophyceae (Green algae) - Bacillariophyceae (Diatoms) - Rhodophyceae (Red algae) 3. **Analyze Cyanophyceae**: This group, also known as blue-green algae, primarily contains chlorophyll a. They do not contain phycoerythrin, so this option can be eliminated. 4. **Analyze Chlorophyceae**: This group consists of green algae, which typically contain chlorophyll a and b. They also do not contain phycoerythrin, so this option can also be eliminated. 5. **Analyze Bacillariophyceae**: This group includes diatoms, which are unicellular algae. They mainly contain chlorophyll a, chlorophyll c, beta-carotene, and fucoxanthin. They do not have phycoerythrin, so this option can be eliminated as well. 6. **Analyze Rhodophyceae**: This group consists of red algae, which are characterized by the presence of chlorophyll a and chlorophyll d. Importantly, they also contain phycoerythrin, which gives them their red color. Since the alga in question contains both chlorophyll d and phycoerythrin, this is the correct classification. 7. **Conclusion**: Based on the analysis, the alga collected by the research scholar must belong to the group Rhodophyceae (Red algae). ### Final Answer: The alga must belong to **Rhodophyceae**.
