The options may tempt you to subtract the readings, but the concept of barometer and manometer is important. Barometer measures the atmospheric pressure whereas, the manometer reads the gauge pressure. Hence, we need to add the two values.

Given Data:
- Barometer reading = 1.3152 bar
- Manometer pressure gauge reading = 0.3152 bar
Calculating Absolute Pressure:
- The absolute pressure at the point below the surface of the water can be calculated using the formula:
Absolute Pressure = Atmospheric Pressure + Gauge Pressure
- The atmospheric pressure is equal to the barometer reading, which is 1.3152 bar.
- The gauge pressure measured by the manometer is 0.3152 bar.
Substitute the values:
Absolute Pressure = 1.3152 bar + 0.3152 bar
Absolute Pressure = 1.6304 bar
Therefore, the absolute pressure of water at a point below the surface is 1.6304 bar. Hence, the correct answer is option B.
