Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The Solanaceae (Potato family) is characterized by specific floral traits represented in its floral formula:
• $\oplus$: Actinomorphic symmetry.
• $\subsetneq$: Bisexual flower.
• $K_{(5)}$: Calyx has 5 sepals, which are gamosepalous (united/fused).
• $C_{(5)}$: Corolla has 5 petals, which are gamopetalous (united/fused).
• $A_{5}$: Androecium has 5 stamens, which are epipetalous (attached to petals).
• $\underline{G}_{(2)}$: Gynoecium is bicarpellary, syncarpous (united), with a superior ovary. Option (1) correctly shows the brackets indicating fusion for both the calyx and corolla, which is essential for Solanaceae.
