To solve the problem of matching List I with List II, we need to understand each term in both lists. Here are the details:
- Rose: Roses typically have perigynous flowers where sepals, petals, and stamens are attached around the edge of a concave structure and not directly beneath a superior ovary, which matches with II.
- Pea: Peas exhibit marginal placentation, where ovules are attached to a single ridge forming the placenta. This matches with IV.
- Cotton: The flower of cotton shows twisted aestivation, where petals overlap in a twisted manner, which corresponds to I.
- Mango: Mango develops from a single ovary and forms a drupe, a type of fruit with a fleshy outer layer surrounding a single seed, which matches with III.
Therefore, the correct matching is A-II, B-IV, C-I, D-III.
