The correct statement is D. The resistance of the lamp increases because the temperature increases.

Here's why:

1. When the potential difference (p.d.) or voltage across a filament lamp is increased, more current is driven through the lamp.

2. This increase in current causes the filament (usually made of tungsten) to heat up.

3. As the temperature of the filament increases, the atoms in the filament vibrate more.

4. This increased vibration makes it harder for the electrons to pass through the filament, effectively increasing the resistance.

5. Therefore, as the temperature increases, the resistance of the lamp also increases.
