Answer:

D. 214 kPa

Step-by-step explanation:

The absolute pressure is given by:


p = p_a + p_g

where

p is the absolute pressure


p_a \sim 100 kPa is the atmospheric pressure


p_g is the gauge pressure

In this problem, we have


p_g = 114 kPa

So, the atmospheric pressure is


p = 100 kPa + 114 kPa = 214 kPa
