The correct Answer is:
To solve the question regarding vexillary aestivation and what the keel represents, we can follow these steps: ### Step-by-Step Solution: 1. **Understand Vexillary Aestivation**: Vexillary aestivation is a type of floral arrangement in which the petals are arranged in a specific manner. In this arrangement, there are typically five petals. 2. **Identify the Petals**: In vexillary aestivation, the petals are categorized as follows: - **Standard Petal**: This is the largest petal and is located at the top (posterior). - **Wings**: These are two lateral petals that are larger than the keel. - **Keel**: This consists of two smaller petals that are located at the bottom (anterior). 3. **Determine the Position of the Keel**: The keel is formed by two small petals that are positioned anteriorly in the flower. They are smaller compared to the standard and wing petals. 4. **Analyze the Options**: - (a) The largest posterior petal - This refers to the standard petal. - (b) Two smaller lateral petals - This refers to the wings. - (c) Two smallest anterior petals - This correctly describes the keel. - (d) The largest anterior petal - This does not apply to any of the petals in vexillary aestivation. 5. **Select the Correct Answer**: Based on the analysis, the keel represents the two smallest anterior petals. Therefore, the correct answer is **(c) Two smallest anterior petals**. ### Final Answer: The keel represents **(c) Two smallest anterior petals**. ---
