The pressure at the summit is always less than atmospheric pressure. So, the highest point according to options is 7.4 that is less than 10.33, so the answer B is correct.

The pressure is only -7.6m of water or 10.3-7.6= 2.7 m of water absolute.
p vacuum = p atm - p absolute.
So maximum vacuum = 10.3-2.7 = 7.6 m.
p vacuum = p atm - p absolute.
So maximum vacuum = 10.3-2.7 = 7.6 m.

It is -7.6 or 10.3 - 7.6 = 2.7m of water.

10.3m of H2O = 76Cm of hg.
1 m of H2O = 7.378.
So, the answer is B.
1 m of H2O = 7.378.
So, the answer is B.
