detailed solution

Correct option is C

at all temperatures the volume of the air inside the flask remains same VCγC=VLγL ; here V is volume of container and volume of liquid; γ coefficient of volume expansion of container and liquid  VL=VCγCγL given VC=2liter;γC=3α=3x9x10-6/C  0;γL=1.8x10-4/C  0, substitute VL=2literx3x9x10-61.8x10-4        since 1liter=10-3m3 VL=300x10-6m3=volume of mercury in the flask
