Correct answer is C: the two beakers are identical, so the area at the bottom of the two liquids is the same.
The other statements, instead, are false.
Statement A is false because the air pressure on top of the two liquids is the same (it is equal to the atmospheric pressure).
Statement B is false because the weight of liquid B is greater than the weight of liquid A, because liquid B is more dense, and the weight is equal to
[tex]mg= \rho V g[/tex]
where [tex]\rho[/tex] is the liquid density and V the volume. Since the volume of the two liquids is the same, the weight of liquid B is greater than the weight of liquid A.
Statement D is false because the pressure at the bottom of beaker B is greater. In fact, the pressure of a column of liquid is
[tex]p= \rho g h[/tex]
where [tex]\rho[/tex] is the density and h is the height of the column of liquid: since the height of the two liquids is the same, but the density of liquid B is greater than the density of liquid A, then its pressure at the bottom is also greater.
