Why, from the perspective of a bird caring for her brood, is it important that begging calls correctly indicate the actual need of the calling chick?
 
  a. She can give the most food to the loudest chick regardless of its need.
  b. Under this system, there are no advantages for a chick if it could emit a hunger call without be-ing hungry.
  c. The female bird is equally related to all of her offspring.
  d. Begging calls are costly signals.
