To solve this problem, we need to match the items in List I with the appropriate descriptions in List II. Let's analyze each item:$\newline \bullet$A. Rose:$\newline$ - Roses typically have a perigynous flower structure, where the ovary is partially embedded in the receptacle.$\newline$ - This matches with II.$\newline \bullet$B. Pea:$\newline$ - Peas exhibit marginal placentation, where the ovules are attached along the margin of the ovary.$\newline$
