Concept: This question tests your knowledge of floral formulas, which are symbolic representations of flower structure, specifically for the family Solanaceae (to which chilli belongs).

Why (B) is correct: The floral formula for chilli (Capsicum annuum), which belongs to the family Solanaceae, is correctly represented by option B. Let's break it down:

• $\oplus$: This symbol indicates an actinomorphic (radially symmetrical) flower.
• $\text{♀}$: This symbol indicates a bisexual flower (possessing both male and female reproductive organs).
• ${\text{K}}_{(5)}$: This denotes a calyx (K) with 5 sepals, which are gamosepalous (fused), indicated by the parenthesis.
• ${\text{C}}_{(5)}$: This denotes a corolla (C) with 5 petals, which are gamopetalous (fused), indicated by the parenthesis.
• ${\text{A}}_5$: This denotes an androecium (A) with 5 stamens.
• ${\text{G}}_{(\underline{2})}$: This denotes a gynoecium (G) with 2 carpels, which are syncarpous (fused), indicated by the parenthesis, and the ovary is superior, indicated by the underline beneath the '2'.

Why other options are wrong:

• (A) Incorrect representation of calyx, corolla, and gynoecium fusion and number.
• (C) Incorrect representation of calyx, corolla, and gynoecium fusion and number.
• (D) Incorrect representation of calyx, corolla, and gynoecium fusion and number.

NEET Tip: Remember the key features of common families like Solanaceae, Fabaceae, and Liliaceae, as their floral formulas are frequently asked. Pay close attention to fusion (parentheses), number of parts, and ovary position (underline).

Correct Answer: (B)
