The Pressure At 10 Below The Surface Of The Ocean Is About2.00×105 .Which Of The Following Statements Istrue?

The pressure at 10 below the surface of the ocean is about2.00×105 .
Which of the following statements istrue?
 The weight of a column of seawater 1 in cross section and 10 high is about 2.00×105 . The weight of a column of seawater 1 in cross section and 10 high plus the weight of a column of air with thesame cross section extending up to the top of the atmosphere isabout 2.00×105 . The weight of 1 of seawater at 10 below the surface of the ocean is about2.00×105 . The density of seawater is about2.00×105 times the density of air at sealevel.
Now consider he pressure at 20 below the surface of the ocean.
This pressure is
 twice that at a depth of 10 . the same as that at a depth of 10 . equal to that at a depth of 10 plus the weight of a column of seawater 1 in cross section and 10 high. equal to the weight of a column of seawater 1 in cross section and 20 high.
