The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Cyathium Inflorescence:** - Cyathium is a type of inflorescence found in plants of the family Euphorbiaceae. It is characterized by a unique arrangement of flowers. 2. **Analyzing the Options:** - **Option A:** "Single female flower surrounded by many male flowers." - In cyathium inflorescence, there is indeed one female flower that is surrounded by several male flowers. This statement is correct. - **Option B:** "Involucre of bracts enclosing all the flowers." - The cyathium is surrounded by bracts that form an involucre, which encloses the flowers. This statement is also correct. - **Option C:** "Fleshy inflorescence axis with a pear-shaped cavity inside." - The structure of the cyathium is fleshy and has a pear-shaped cavity that contains the flowers. This statement is correct as well. - **Option D:** "Chlamydeous flowers." - Chlamydeous flowers have petals and sepals. However, the flowers in cyathium are typically described as achlamydeous, meaning they lack these structures. Therefore, this statement is incorrect. 3. **Conclusion:** - Since options A, B, and C are correct, and option D is incorrect, the correct answer is that cyathium inflorescence is characterized by A, B, and C. **Final Answer: A, B, and C are correct.** ---
