Complete answer:
Opium poppy or bread seed poppy is a flowering plant that belongs to the family Papaveraceae. The opium seeds and poppy are derived from this plant. This plant is mainly used for pharmaceutical purposes. It has a greyish-green appearance with large lobed leaves, mauve or red flowers. The fruit of this plant is hairless and looks like a rounded capsule. This capsule has 12 to 18 stigmatic rays spreading out from it. These fruits have multiple seeds and belong to the dry dehiscent fruits category. Dehiscence is the mechanism through which a part of a plant split usually for seed dispersal. They contain some sort of seed-pod to release seeds. In opium, poppy dehiscence occurs through the formation of pores.

Option A) pepo fruits are ones which are fleshy and watery. They have several seeds and a from the rind. Examples are cucumber, melon etc. Therefore this is an incorrect option.
Option B) Berries are usually small and bright coloured. They are pulpy with a sour or tart flavour. Examples are blueberries, strawberries etc. Therefore this is an incorrect option.
Option C)Loculicidal capsules belong to plants having dry and dehiscent fruits. Their dehiscence occurs by the splitting up of the midrib or locule of ovaries. These types of fruits are usually seen in fruits of violet and lily families. Therefore this is an incorrect option.
Option D) Poricidal capsules are fruits bearing pores. In these, dehiscence occurs through the formation of pores. Therefore this is the correct option.

Hence, the correct answer is option (D)

Note: In opium poppy, the fruits are dry and dehiscent. It is developed from a multi capillary syncarpous ovary. Loculicidal capsules will result in the formation of longitudinal cuts in the ovary due to dehiscence whereas berry and pepo are succulent fruits.
