Answer: C

Gauge pressure = 156 kPa ,

What is absolute pressure =?

     We know that,

      absolute pressure = gauge pressure + atmospheric pressure

                           Pabs = Pgauge + Patm

                                     = 156 + 101.3             (since atm.pr. = 101.3 Kpa)

                                     = 257.3 KPa absoulte

                                     approximately  = 256 KPa absolue
