Answer 1

Wrong words . it's not inspiration and expiration . it's inhalation and exhalation .

And the answer is exhalation

Answer 2

Inspiration: Diaphragm contracts

Expiration : Diaphragm relaxes

Inspiration and inhalation are synonyms and so are expiration and exhalation.

Inspiration: The drawing of air into the lungs, accomplished by elevation of the chest walls and flattening of the diaphragm, as part of the act of respiration.

Expiration: The act or process of breathing out, or forcing air from the lungs through the nose or mouth accomplished by relaxation of diaphragm.
