Given data:
- Capacitance, C = 4 μF = 4 × 10^-6 F
- Voltage, V = 400 V
- Resistance, R = 1 kΩ = 10^3 Ω

Calculating Energy Stored in the Capacitor:
- The energy stored in a capacitor is given by the formula: E = 0.5 * C * V^2
- Substituting the given values, we get: E = 0.5 * 4 × 10^-6 * (400)^2
- E = 0.5 * 4 × 10^-6 * 160000
- E = 0.32 J

Calculating Heat Produced in the Resistor:
- When the plates of the capacitor are joined through the resistor, the energy stored in the capacitor is dissipated as heat in the resistor.
- The heat produced in the resistor is equal to the energy stored in the capacitor, which is 0.32 J.
Therefore, the correct answer is option 'D' (0.32 J).
