Concept: This question tests your knowledge of floral morphology, specifically the position of the ovary in relation to other floral parts in the ray florets of a sunflower.

Why (B) is correct: The ray florets of a sunflower (Helianthus annuus), which belongs to the family Asteraceae (Compositae), exhibit an inferior ovary. In an inferior ovary, the ovary is situated below the attachment point of the sepals, petals, and stamens, which appear to arise from the top of the ovary.

Why other options are wrong:

• (A) half inferior ovary: This condition is intermediate, where the ovary is partially embedded, not fully inferior as in sunflower ray florets.
• (C) superior ovary: In a superior ovary, the ovary is positioned above the attachment point of other floral parts.
• (D) hypogynous condition: This condition is associated with a superior ovary, where the floral parts are attached below the ovary.

NEET Tip: Remember that members of the Asteraceae family (like sunflower and marigold) typically have an inferior ovary. This is a characteristic feature often tested.

Correct Answer: (B)
