A soap bubble assumes a spherical surface. Which of the following statement is wrong

• A

  The soap film consists of two surface layers of molecules back to back

• B

  The bubble encloses air inside it

• C

  The pressure of air inside the bubble is less than the atmospheric pressure; that is why the atmospheric pressure has compressed it equally from all sides to give it a spherical shape

• D

  Because of the elastic property of the film, it will tend to shrink to as small a surface area as possible for the volume it has enclosed
