Before Inspiration, Alveolar Pressure Is 0 and Intrapleural Pressure Is $+ 2$

Before inspiration, alveolar pressure is 0 and intrapleural pressure is -5 cm H₂O. At the end of an inspiration in a healthy person, with the glottis open, these readings would be: A. Alveolar pressure of $+ 2$ , intrap leural pressure of $- 8 \mathrm {~cm} \mathrm { H } _ { 2 } \mathrm { O }$
B. Alveolar pressure of $- 2$ , intrapleural pressure of $- 8 \mathrm {~cm} \mathrm { H } _ { 2 } \mathrm { O }$
C. Alveolar pressure of 0 , intrapleural pressure of $+ 5 \mathrm {~cm} \mathrm { H } _ { 2 } \mathrm { O }$
D. Alveolar pressure of 0 , intrapleural pressure of $- 5 \mathrm {~cm} \mathrm { H } _ { 2 } \mathrm { O }$
E. Alveolar pressure of 0 , intrapleural pressure of $- 8 \mathrm {~cm} \mathrm { H } _ { 2 } \mathrm { O }$
