To verify Ohm's law, a student connects the voltmeter across the battery as shown in the figure. The measured voltage is plotted as a function of the current, and the following graph is obtained.

If V$$_0$$ is almost zero, identify the correct statement:

A

The emf of the battery is 1.5 V and its internal resistance is 1.5 Ω

B

The value of the resistance R is 1.5 Ω

C

The potential difference across the battery is 1.5 V when it sends a current of 1000 mA

D

The emf of the battery is 1.5 V and the value of R is 1.5 Ω
