Explanation:
The given statements are related to the respiratory system of mammals. Let us evaluate each statement to determine the correct ones.
(i) Mammals have negative pressure breathing: This statement is correct. Mammals use negative pressure breathing, which involves the expansion of the thoracic cavity and lungs by the contraction of the diaphragm and intercostal muscles.
(ii) The impulses for voluntary breathing are sent by the medulla oblongata: This statement is correct. The medulla oblongata is responsible for regulating involuntary breathing, but it also receives input from higher brain centers that control voluntary breathing.
(iii) The trachea, primary, secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings: This statement is incorrect. The trachea, primary, secondary and tertiary bronchi, and initial bronchioles are supported by complete cartilaginous rings.
(iv) The volume of air remaining in the lungs even after a forcible expiration is functional residual capacity: This statement is correct. Functional residual capacity is the volume of air that remains in the lungs after a normal expiration.
Therefore, out of the given statements, three statements are correct, and one statement is incorrect. Hence, the correct option is (b) Three.

i. Reptiles, birds and mammals possess negative pressure breathing.
ii. The impulses for voluntary breathing are sent by the medulla oblongata.
iii. The primary, secondary and tertiary bronchi are supported by incomplete cartilaginous rings.
iv. The volume of air remaining in the lungs after a normal expiration is known as functional residual capacity (FRC). It includes expiratory reserve volume (ERV) and residual volume (RV). ERV is the maximum volume of air that can be exhaled after a normal expiration. It is approximately 1000–1500 mL.
