The correct Answer is:
To solve the question, we need to analyze each statement provided and determine whether they are correct or not. ### Step-by-Step Solution: 1. **Statement A**: "Fleshy cylindrical stem in Euphorbia carries out photosynthesis." - **Analysis**: Euphorbia has fleshy stems that contain chlorophyll, allowing them to perform photosynthesis. This statement is **correct**. 2. **Statement B**: "Pistia and Eichhornia are examples of offset." - **Analysis**: Offsets are a type of vegetative reproduction where a lateral branch with short internodes and rosettes of leaves develops. Both Pistia (water lettuce) and Eichhornia (water hyacinth) are aquatic plants that reproduce this way. This statement is **correct**. 3. **Statement C**: "Underground stem of grass and strawberry spread to new niche and when older part die new plants are formed." - **Analysis**: Grass and strawberries have underground stems (like rhizomes) that can spread to new areas. When older parts die, new plants can indeed form from these underground stems. This statement is **correct**. 4. **Statement D**: "Thorns are woody, straight, and pointed." - **Analysis**: Thorns are indeed hard, woody structures that are often straight and pointed. They can be found in various plants, such as citrus. This statement is **correct**. ### Conclusion: Since all four statements A, B, C, and D are correct, the correct answer is **all of these**.
