Concept: This question tests your understanding of floral diagrams and their corresponding floral formulas, which are symbolic representations of flower structure.

Why (D) is correct: Let's analyze the given floral diagram:

1. Symmetry: The flower shows actinomorphic symmetry (radial symmetry), indicated by a circle with a plus sign $\oplus$.
2. Bracteate/Ebracteate: There is no bract shown, so it's ebracteate.
3. Calyx (K): There are 5 sepals, which are free (valvate aestivation). So, K₅.
4. Corolla (C): There are 5 petals, which are free (valvate aestivation). So, C₅.
5. Androecium (A): There are 5 stamens, which are free and alternate with the petals. So, A₅.
6. Gynoecium (G): There are 2 carpels, which are fused (syncarpous), and the ovary is superior (indicated by a line below G). So, G₍₂₎.

Combining these, the floral formula is $\oplus$ K₅ C₅ A₅ G₍₂₎, which matches option D.

Why other options are wrong:

• (A) Incorrect symmetry (zygomorphic) and incorrect number of stamens.
• (B) Incorrect symmetry (zygomorphic) and incorrect number of stamens.
• (C) Incorrect symmetry (zygomorphic) and incorrect number of stamens.

Common Mistake: Students often confuse actinomorphic and zygomorphic symmetry, and misinterpret the fusion or freeness of floral parts from the diagram.

NEET Tip / Mnemonic: Remember that a line below G indicates a superior ovary, and a line above G indicates an inferior ovary. Fusion is shown by parentheses around the number, e.g., K₍₅₎.

Correct Answer: (D)
