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

The pressure at 10below the surface of the ocean is about2.00×105.
Which of the following statements istrue?
 The weight of a column of seawater 1in cross section and 10high is about 2.00×105. The weight of a column of seawater 1in cross section and 10high 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 1of seawater at 10below 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 20below 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 1in cross section and 10high. equal to the weight of a column of seawater 1in cross section and 20high.
