The correct Answer is:
To determine the correct combinations from the given options, we will analyze each one step by step. ### Step 1: Analyze the First Combination **Combination:** Cymose inflorescence - Epipetalous - Solanum - **Cymose Inflorescence:** Solanum belongs to the family Solanaceae and exhibits cymose inflorescence, which is characterized by determinate growth where flowers are borne terminally on the floral axis. - **Epipetalous:** In Solanum, the stamens are attached to the petals, which is the definition of epipetalous. **Conclusion:** This combination is correct. ### Step 2: Analyze the Second Combination **Combination:** Homochlamydeous - Polyandrous - Allium - **Homochlamydeous:** This term refers to flowers that have petals of the same color and shape. Allium (onion family) does not strictly fit this description as it can have varied petal shapes and colors. - **Polyandrous:** In Allium, the stamens are numerous and free, which fits the definition of polyandrous. **Conclusion:** Since the first part is incorrect, this combination is incorrect. ### Step 3: Analyze the Third Combination **Combination:** Axile placentation - Radial leaves - Smilax - **Axile Placentation:** Smilax does exhibit axile placentation. - **Radial Leaves:** However, Smilax does not have radial leaves; it typically has alternate or whorled leaves. **Conclusion:** Since the second part is incorrect, this combination is incorrect. ### Step 4: Analyze the Fourth Combination **Combination:** Zygomorphic - Diadelphous - Butea - **Zygomorphic:** Butea (Butea monosperma) is zygomorphic, meaning it has bilateral symmetry. - **Diadelphous:** In Butea, the stamens are united in two bundles, which is characteristic of diadelphous flowers. **Conclusion:** This combination is correct. ### Final Conclusion The correct combinations are: - **First Combination:** Cymose inflorescence - Epipetalous - Solanum (Correct) - **Fourth Combination:** Zygomorphic - Diadelphous - Butea (Correct) Thus, the answer is that the first and fourth combinations are correct. ---
