The correct option is D All of the above
Thalamus is the edible part of all the fruits mentioned above. The edible part of these fruits is the receptacle which turns fleshy, juicy and colourful. If we cut the fruit then we can see a clear demarcation of the inner fruit which is a true fruit in botanical terms. These fruits are developed from the ovary and seeds from the ovule. The true fruit is deep inside the fleshy thalamus that we eat. So, the edible part cannot be called as a true fruit. The inner fruit is a true fruit while the outer fleshy part is not.
Thus, the correct answer is option D.
