Concept: This question tests your understanding of flower morphology, specifically the position of the ovary relative to other floral parts, which determines if a flower is hypogynous, perigynous, or epigynous.

Why (D) is correct: A perigynous flower has its ovary situated in a cup-shaped or saucer-shaped receptacle, and the other floral parts (sepals, petals, stamens) arise from the rim of this cup, appearing to be at the same level as the ovary. The ovary is said to be half-inferior. Examples of plants with perigynous flowers include members of the family Rosaceae, which includes plum, peach, and rose. Therefore, all the options listed exhibit perigynous ovaries.

Why other options are wrong: Since plum, peach, and rose all have perigynous ovaries, selecting any single option (A, B, or C) would be incomplete.

NEET Tip: Remember the mnemonic 'PPR' for Perigynous: Plum, Peach, Rose. For Hypogynous (superior ovary), think 'Mustard, China rose, Brinjal'. For Epigynous (inferior ovary), think 'Guava, Cucumber, Ray florets of Sunflower'.

Correct Answer: (D)
