Solution
Sol. [Key Concept: Floral morphology examples]
Rose is perigynous (A–II); pea has marginal placentation (B–IV); cotton has twisted aestivation (C–I); mango produces a drupe (D–III). Hence, option (3). NCERT uses the term half-inferior for this perigynous arrangement. Structurally, the hypanthium is not fused to the ovary; this distinguishes perigyny from the fused inferior ovary of epigyny.
