Hint:A wading bird is a long-legged bird, such as a crane, heron, or stork,that frequents shallow water, especially in search of food. Also called wader.

Complete Answer:
All of these birds belong to the order of Ciconiiformes, let us know more about them-
1) Birds of the order Ciconiiformes have long legs and that is why they are called Wader birds. Some examples are Flamingo, Kingfisher, Grey Heron.
2) They have long legs so that they can stand in water and hunt. Because flamingos have long legs, they can wade into much deeper water than most other birds. Webbed feet support them on soft mud. When the water is beyond their wading depth, flamingos swim at the surface while feeding. Webbed feet allow the flamingo to swim quite readily.
3) An unusual adaptation kingfisher possesses is the ability to compensate for the water's refraction and reflection as they search for prey underwater.
4) This makes the fish look closer to the surface than it is. They have accurate depth perception as well. Nature has provided the Kingfisher with a great deal of ocular protection. This adaptation combined with long legs and a long neck allows these herons to forage successfully in a variety of aquatic environments and on an extensive menu of prey. Their bill is adapted for probing, grasping, and on occasion spearing prey.
The above discussion proves that all of them are waders or wading birds.

Hence, the answer is D (All of the above).

Note:Wading birds often are gregarious in nature, nesting, feeding, and migrating in large flocks. The waders usually fly in large flocks where they have their legs fully extended, often extending past the tail.
