Two beakers of capacity 500 mL were taken. One of these beakers, labelled as A, was filled with 400 mL water, whereas the other beaker is labelled as 'B' was filled with 400 mL of 2 M solution of NaCl.At the same temperature both the beakers were placed in closed containers of same material and same capacity as shown in figure. At a given temperature, which of the following statement is correct about the vapour pressure of pure water and that of NaCl solution?
