Explanation of the correct option:
- The pharynx, oesophagus, crop, proventriculus, gizzard, small intestine, and large intestine make up the digestive system of most aves.

The mouth, teeth, and gill rakers, oesophagus, stomach, pylorus, pyloric caeca, pancreatic tissue (exocrine and endocrine), liver, gall bladder, intestine, and anus are all structural components of an Osteichthyes digestive system.
Option B:
A mouth, oesophagus, stomach, and intestine comprise an amphibian's digestive tract, which culminates in a compartment known as the cloaca.
Option C:
The mouth and salivary glands, the oesophagus, the stomach, and the intestine make up the digestive system of reptiles, which finishes in a cloaca.
Final answer: Aves are the group of animals characterized by crop and gizzard in its digestive system.
