Anybody, please explain to me that why piezometer can not be used for high-pressure measurement?

According to NPTEL, Manometers are used to measure large gauge pressures. So option C is correct.

Piezometer is use to measure low or Moderate pressure either Manometer is use to measure High pressure or pressure at a point.
Barometer is used to measure Atmospheric pressure.
It is correct.
Barometer is used to measure Atmospheric pressure.
It is correct.

If manometer is used to measure high pressure then why we use mechanical gauges like Bourdon pressure gauge. We generally use Bourdon pressure gauge in labs to measure high pressure.
So, guys, manometers are used to measuring low pressure or moderate pressure.

@Gautam Sahni.
We can measure high pressure by piezometer but for this, we should have large piezometer (2 meters, 3 meters or more) to measure high pressure and it should be installed in the vertical direction so it is difficult to take a reading for us. So we don't use piezometer to measure high pressure. Mechanical gauge is used to measure high pressure.
So the answer to the above question is A&B.
I hope now it is clear.

Manometer is used to measure.
1) High Pressure.
2) Vaccum Pressure.
3) pressure in pipes and channel, etc.

Piezometer is used to measure moderate pressure and manometer is used to measure high pressure or pressure in pipes and channels.

Piezometer for low and moderate pressure, manometer for high pressure, pressure in vacuum and pipes and barometer for atmospheric pressure.

Simple Manometer is used to measures low pressure because one of its ends is open to atmosphere, if liquid pressure is higher than atm pr then high-density liquid will fall from right limb.
