Solution

The correct option is A Assertion is false but Reason is true
The three chalazal cells of the embryo sac are called antipodal cells. They are the vegetative cells of the embryo sac which may degenerate soon or take part in absorbing nourishment from the surrounding nucellar cells. Internally they are connected with the central cell by means of plasmodesmata.
So, the correct answer is 'Assertion is false but Reason is true'
