The correct option is B Inspiratory reserved volume
Inspiratory reserve volume is the quantity of air that can be forcefully inspired after a normal tidal inspiration. It is 3.1 litres in men and 1.9 litres in a woman. When IRV combines with tidal volume it is known as inspiratory capacity of lungs.
So, the correct answer is option B.
