Detailed explanation-1: -Hibiscus and papaver are the plants that contain multicarpellary and syncarpous gynoecium. So, the correct answer is option D, More than one option.

Detailed explanation-2: -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).

Detailed explanation-3: -Multicarpellary means the gynoecium consists of more than one pistil and apocarpous means the pistil is free and not attached. An example of multicarpellary apocarpous gynoecium is the gynoecium of strawberries. Lotus and Rose also have such gynoecium.

Detailed explanation-4: -The total number of carpels is variable; in Papaver there are 4-16 carpels; in Argemone 4-6 carpels; in Platystemon numerous carpels and the ovary also becomes multilocular. In Chelidonium there are only two carpels.
