Correct answer: C

Expiratory Capacity (EC) is the total volume of air a person can expire after a normal inspiration. This includes tidal volume and expiratory reserve volume.


Since, Tidal Volume = 500 ml


And Expiratory Reserve Volume = 1000 ml


So, Expiratory Capacity = TV + ERV = 500 + 1000 = 1500 ml
