Potential energy = m * g * h ( m = mass, g = acc. due to gravity, h = height of object )

acceleration due to gravity would be same in each case.
height will the factor 
3rd one will be the correct answer because when you are standing ur centre of gravity will be raised up while when you are sitting it will be below compared to when u r standing and the center of gravity will be least in the case when u r sleeping on ground.
So, 3rd option will be the correct answer.
