In the given circuit, it is observed that the current $I$ is independent of the value of the resistance $R_6$. Then the resistance values must satisfy
  • A${R_1}{R_2}{R_5} = {R_3}{R_4}{R_6}$
  • B$\frac{1}{{{R_5}}} + \frac{1}{{{R_6}}}$$ = \frac{1}{{{R_1} + {R_2}}} + \frac{1}{{{R_3} + {R_4}}}$
  • C${R_1}{R_4} = {R_2}{R_3}$
  • D${R_1}{R_3} = {R_2}{R_4} = {R_5}{R_6}$
