The correct option is A a - multicarpellary syncarpous pistil and b - multicarpellary apocarpous pistil
In Papaver, gynoecium consists of many carpels (multicarpellary) and the carpels are fused together (syncarpous pistil). While in Michelia also, gynoecium consists of many carpels (multicarpellary) but the carpels are free (apocarpous pistil).
