Why (B) is correct:
A half-inferior ovary (also known as perigynous flower) is one where the ovary is partially embedded in the thalamus, and the other floral parts (sepals, petals, stamens) arise from the rim of the cup-shaped thalamus at the same level as the ovary. Among the given options, Peach, Plum, and Rose are examples of plants with half-inferior (perigynous) flowers.
Why other options are wrong:
- Mustard has a superior ovary (hypogynous flower).
- Brinjal (eggplant) has a superior ovary (hypogynous flower).
Common Mistake: Students often confuse the terms hypogynous, perigynous, and epigynous, which describe the position of the ovary relative to other floral parts.
NEET Tip / Mnemonic: Remember 'PPR' for Perigynous (half-inferior ovary): Peach, Plum, Rose. For superior ovary (hypogynous), think 'MB' for Mustard, Brinjal.
Correct Answer: (B)
