A closed circuit shown in the adjacent figure includes a resistor of resistance $$20.0\,\Omega$$ and battery of emf $$3.0\,\mathrm{V}$$ and internal resistance of $$1\,\Omega$$. The internal resistance of the battery can be considered in series with it. The voltage drop across the resistor of resistance $$20\,\Omega$$ is

A

$$2.857\,\mathrm{V}$$

B

$$3.000\,\mathrm{V}$$

C

$$2.500\,\mathrm{V}$$

D

$$1.567\,\mathrm{V}$$
