$\huge\tt\pink{\boxed{\tt{\blue{★\:Answer}}}}$

A.Tidal volume - Volume of air inspired or expired with each normal breath 

B.Inspiratory capacity - the volume of air that can be inspired following a normal, quiet expiration and is equal to tidal volume + inspiratory reserve volume.

C.Total lung capacity - the total amount of air in the lungs after taking the deepest breath possible. Patients with chronic obstructive pulmonary disease (COPD) are often unable to exhale fully, resulting in hyperinflation of the lungs and a greater total lung capacity.

D.Residual volume - the amount of air that remains in a person's lungs after fully exhaling.
