The maximum volume of air a person can breathe in after a forced expiration is $:-$

In a normal adult human, four respiratory capacities $(i-iv)$ and four respiratory volumes are given below. Which one of the following is the correct matching of two capacities and volumes?

Respiratory Capacity/Volume	Volume $(mL)$
$(i)$ Residual Volume $(RV)$	$2500$ $mL$
$(ii)$ Vital Capacity $(VC)$	$3500$ $mL$
$(iii)$ Inspiratory Reserve Volume $(IRV)$	$1200$ $mL$
$(iv)$ Inspiratory Capacity $(IC)$	$4500$ $mL$

What is Functional Residual Capacity $(FRC)$?

What is the volume of air inspired or expired during a normal respiration called?

Define vital capacity. What is its significance?
