In the adjacent circuit, the voltages across AD, BD and CD are $$2\text{ V}$$, $$6\text{ V}$$ and $$8\text{ V}$$ respectively. If resistance $$R_A=1\text{ k}\Omega$$, then the values of resistances $$R_B$$ and $$R_C$$ are

A

$$4\text{ k}\Omega$$ and $$6\text{ k}\Omega$$

B

$$2\text{ k}\Omega$$ and $$1\text{ k}\Omega$$

C

$$1\text{ k}\Omega$$ and $$2\text{ k}\Omega$$

D

data insufficient as battery voltage is not given
