According to the formula of Capacitance, $$
C= \frac {ε_{0}\times A} {d}
$$

Here, 

  • ε0 is the permittivity of free space
  • A is the area of the plates
  • d is the distance between the plates.
  1. Reducing the area reduces capacitance, as a smaller area decreases charge storage capacity.
  2. Increasing the distance decreases capacitance by increasing the separation between plates, hence reducing charge attraction.
  3. Increasing the area enhances capacitance, as a larger surface allows the storage of greater charge.
  4. None of the above is incorrect, as increasing the area improves capacitance.

Hence, the correct answer is option 3)Increasing the area.
