Answer:
C) They are compressed during inhalation.
Explanation:
Birds breathe through rigid lungs that are located in the animal's thoracic region. The trachea of birds divides into bronchi that branch inside the lungs into very thin tubes called parabronchials or parabroncholes, which are irrigated by blood capillaries that allow gas exchange.
In birds there are no pulmonary alveoli (as in mammals), but air capillaries that depart from the parabroncholes. Oxygen gas passes from these capillaries to the blood capillaries, thus causing gas exchange.
In the lower portion of the bird's trachea, before branching the bronchi, we can find the syringe, a bag-like structure that has vocal cords responsible for the birds' scream and song. Most of the time, the sound emitted by birds serves to attract the mate, mark territory and prevent birds of the same species against some predator or other danger.

The answer is an abdominal cavity.
The abdominal cavity refers to a space that comprises various essential organs including the stomach, the lower part of the esophagus, colon, small intestine, gallbladder, liver, rectum, bladder, spleen, and kidneys.
The abdominal cavity is a big cavity found in humans and various other animals. It is a component of abdominopelvic cavity. It is situated above the pelvic cavity and below the thoracic cavity. Its dome-shaped roof is the thoracic diaphragm, a thin sheet of muscles beneath the lungs, and its floor is the pelvic inlet, opening into the pelvis.
