The correct option is D Castor
The endosperm is the storage tissue of the seed and provides nourishment to the growing seedling at germination. In some groups (e.g., grains of the family Poaceae) the endosperm persists in the mature seed stage as a storage tissue. These types of seeds are called as albuminous or endospermous seeds. e.g., Castor.
So, the correct answer is 'Castor'
