Solution

The correct option is A Castor

Castor-oil seed is dicotyledonous (having two cotyledons), endospermic (with a special food storing tissue called endosperm) and perispermic (having perisperm or persistent nucellus). It is a white spongy bilobed outgrowth present near the narrow end of the seed. If partially covers the hilum (dark scar) and completely covers the micropyle (small pore). It absorbs water which percolates through the micropyle into the seed. So, the correct answer is 'Castor'.
