In the circuit below, the battery has an internal resistance $r$ and an emf $\varepsilon$. A variable resistor $R$ is connected in the circuit and the ammeter and voltmeter register readings.

The resistance of the variable resistor $\mathrm{R}$ is INCREASED now.

Which ONE of the following combinations is the CORRECT representation of the change in the readings on the ammeter and voltmeter as the resistance of $\mathrm{R}$ is increased?
