What is Functional Residual Capacity $(FRC)$?

What is the Vital Capacity $(VC)$ of our lungs?

If the respiratory rate of $A$ is $35$ breaths/min and tidal volume is $185 \, cc/breath$, and for $B$ it is $25$ breaths/min and tidal volume is $259 \, cc/breath$, then:

The total lung capacity $(TLC)$ is the total volume of air accommodated in the lungs at the end of a forced inspiration. This includes:

Complete the missing terms:
$(a)$ Inspiratory Capacity $(IC) = \dots \dots + IRV$
$(b)$ $\dots \dots = TV + ERV$
$(c)$ Functional Residual Capacity $(FRC) = ERV + \dots \dots$

Which of the following has the lowest value?
