Physics Surface Tension Pressure Difference MCQ (Single Correct)

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 enclose
