As suggested by the figure, the plates of capacitors A and C are separated by a distance d while those of B and D are separated by a distance 2d. Capacitors A and B are maintained in vacuum while capacitors C and D contain dielectrics with constant k = 5.

Which list below places the capacitors in order of increasing capacitance?

  1. A, B, C, D    
  2. B, A, C, D    
  3. B, A, D, C    
  4. A, B, D, C
