Why (A) is true: In brinjal (Solanum melongena), the ovary is indeed superior. This means it is positioned above the attachment points of the sepals, petals, and stamens.
Why (R) is true: The definition of a superior ovary is that the gynoecium (female reproductive part, containing the ovary) occupies the highest position on the thalamus, and the other floral parts (sepals, petals, stamens) are attached below it. This describes the condition of a superior ovary.
Why R is not the correct explanation of A: While both statements are true and describe the same phenomenon, R is essentially the definition of a superior ovary, not a causal explanation for *why* brinjal has a superior ovary. The assertion states a fact about brinjal, and the reason provides the general definition of that fact. It doesn't explain the specific evolutionary or developmental reason for brinjal's ovary position.
Common Mistake: Students often confuse the definition of a superior/inferior ovary with the specific examples. Remember that the 'reason' must explain 'why' the assertion is true, not just define a term used in the assertion.
NEET Tip: For ovary positions, remember the terms: Hypogynous (superior ovary, other parts below), Perigynous (half-inferior ovary, other parts around), and Epigynous (inferior ovary, other parts above).
Correct Answer: (B)
Both A and R are true, but R is not the correct explanation of A.
