Which fruit has edible cotyledon and testa respectively?

The fruit that features an edible cotyledon and testa is the groundnut, which is also known as peanut. Groundnuts are classified as legumes, and their cotyledons are rich in protein and healthy fats, making them an excellent source of nutrition. In seeds, the cotyledons serve as the first leaves that provide nutrition to the developing plant. The testa, or seed coat, of the groundnut is also edible, though it is often removed for culinary purposes.

In contrast, while pomegranates are delicious and consumed widely, they primarily consist of juicy arils that contain the seeds rather than being notable for their cotyledons or testa being the edible parts. Thus, the combination of groundnut and pomegranate correctly identifies the fruit (groundnut) known for its edible cotyledon and the pomegranate which does not fit this criteria regarding its seed structure. This makes the selected answer accurate in highlighting these key characteristics of the plants involved.
