Concept: This question tests your knowledge of floral morphology, specifically the attachment of stamens (androecium) to other floral parts.

Why (A) is correct: In lily (Lilium), the stamens are attached to the perianth (tepals), which is a collective term for sepals and petals when they are not differentiated. This condition, where stamens are attached to the perianth, is called epiphyllous. Since lilies have a perianth, the stamens are epiphyllous.

Why other options are wrong:

• (B) brinjal: Brinjal (Solanum melongena) belongs to the family Solanaceae, where the stamens are typically attached to the petals (corolla), a condition known as epipetalous.
• (C) pea: Pea (Pisum sativum) belongs to the family Fabaceae, where stamens are typically free or united in various ways (e.g., diadelphous), but not epiphyllous or epipetalous.
• (D) mustard: Mustard (Brassica campestris) belongs to the family Brassicaceae, where stamens are typically free and tetradynamous (six stamens, four long and two short), not epiphyllous.

NEET Tip: Remember that 'epi' means 'upon' or 'attached to'. So, epipetalous means attached to petals, epiphyllous means attached to perianth (tepals), and episeplous means attached to sepals (rare).

Correct Answer: (A)
