The correct option is B Tomato
Ovary develops into the fruit post fertilisation.
Tomato is an example of fleshy fruit as the pericarp (fruit wall) is fleshy and differentiated into an outer epicarp, middle mesocarp and inner endocarp.
In tomato, both pericarp (fruit wall) and placenta (tissue to which the ovules are attached) are edible.
Edible parts of other fruits given in the options:
Apple - Thalamus
Banana - Mesocarp and endocarp
Potato - Underground stem (tuber)
So, the correct answer is option C.
