Expert Solution
Step 1

solution 

1.barometer measures atmospheric pressure 

while the manometer pressure difference between two limbs

option 4

2.

while equating the pressure at datum 1-2

on left limb absolute pressure be P1

on right limb absolute pressure is = Patm +ρgh  ( ρ = density of water ;g= acceleration due to gravity ; h = heigth till datum )

on equating 

P1= Patm+ρgh

option 1
