Solution
The correct option is B B and C
In this diagram, Rosa has flask-shaped perigynous as the margin of the thalamus upwardly to produce a hollow flask with gynaecium at its bottom and remaining floral parts at the mouth of the flask. And Prunus have cup-shaped perigynous as the margin of the thalamus is turned upwardly to form a cup or saucer. Gynaecium grows from the bottom of the cup while remaining floral organs are born at the rim of the thalamus.
So, the correct answer is 'B and C'.
