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

Why (A) is correct:

The floral diagram shows the following features:

• Actinomorphic symmetry ($\oplus$): The flower can be divided into two equal halves by any vertical plane passing through the center.
• Bisexual flower ($\text{☿}$): Both androecium (male) and gynoecium (female) are present.
• Calyx (K): 5 sepals, free (not fused). So, ${\text{K}}_5$.
• Corolla (C): 5 petals, free. So, ${\text{C}}_5$.
• Androecium (A): Many stamens (infinity symbol), free. So, ${\text{A}}_{\infty }$.
• Gynoecium (G): Many carpels (infinity symbol), superior ovary (indicated by a line below G), and free carpels. So, ${\text{G}}_{\underline{\infty }}$.

Combining these, the floral formula is $\oplus \text{☿}{\text{K}}_5{\text{C}}_5{\text{A}}_{\infty }{\text{G}}_{\underline{\infty }}$. This matches option A.

Why other options are wrong:

• (B) is incorrect: It shows fused sepals (${\text{K}}_{(5)}$) and fused petals (${\text{C}}_{(5)}$), which is not depicted in the diagram.
• (C) is incorrect: It shows fused sepals (${\text{K}}_{(5)}$) and a different number of stamens and carpels.
• (D) is incorrect: It shows fused sepals (${\text{K}}_{(5)}$) and a different number of stamens and carpels.

Common Mistake: Students often confuse the symbols for fused vs. free parts, and superior vs. inferior ovary. Remember parentheses for fusion and the line position for ovary type.

NEET Tip / Mnemonic: Practice drawing floral diagrams and writing formulas for common families like Fabaceae, Solanaceae, and Liliaceae. Pay close attention to the small details like fusion and ovary position.

Correct Answer: (A)
