A metal foil of negligible thickness is introduced between two plates ...

Explanation:

- When a metal foil of negligible thickness is introduced between two plates of a capacitor, it acts as a conductor connecting the two plates.
- This conductor effectively short circuits the capacitor plates, making them act as one large plate.
- The addition of the metal foil increases the area of the plates but does not affect the distance between them.
- The capacitance of a parallel plate capacitor is given by the formula C = εA/d, where ε is the permittivity of the material between the plates, A is the area of the plates, and d is the distance between the plates.
- Since the metal foil effectively increases the area of the plates, the capacitance of the capacitor remains the same.
- Therefore, the new capacitance of the capacitor with the metal foil introduced is the same as the original capacitance C.

Therefore, the correct answer is option B) C.
