Concept: This question tests your knowledge of floral formulas and the plant families they represent, specifically focusing on the Solanaceae family.

Why (C) is correct: The floral formula $\oplus {\text{K}}_{(5)}{\text{C}}_{(5)}{\text{A}}_5{\text{G}}_{(2)}$ is characteristic of the family Solanaceae. Both Tomato (Solanum lycopersicum) and Brinjal (Solanum melongena) belong to the Solanaceae family. Key features include actinomorphic symmetry ($\oplus$), fused sepals ($ext{K}_{(5)}$), fused petals ($ext{C}_{(5)}$), five stamens ($ext{A}_5$), and a superior, bicarpellary, syncarpous ovary ($ext{G}_{(2)}$).

Why other options are wrong:

• (A) Onion, Garlic: These belong to the family Liliaceae, which has a different floral formula, typically $extBr\oplus {\text{P}}_3+3{\text{A}}_3+3{\text{G}}_{(3)}$.
• (B) Pea, Bean: These belong to the family Fabaceae (Leguminosae), which has a zygomorphic floral formula, typically $\%{\text{K}}_{(5)}{\text{C}}_{1+2+(2)}{\text{A}}_{(9)+1}{\text{G}}_1$.
• (D) All of these: Incorrect, as only Tomato and Brinjal fit the given floral formula.

NEET Tip: Memorize the floral formulas and key characteristics of the major plant families (Fabaceae, Solanaceae, Liliaceae) as they are frequently tested in NEET.

Correct Answer: (C)
