The correct option is D All the above

The utricular gland is a large whitish gland which is made up of two kinds of glandular tubules.

• The peripheral, long, slender tubules utriculi majors, whose secretion also forms the covering of spermatophore.
  
• The central, short tubules, utriculi breviores, whose secretion nourishes the sperms.
  
• The mushroom-shaped glands store the food.
  
• So the correct answer is 'All the above'.
