Correct Answer: Option D — The current flow through 'R1' will differ from the current flow through 'R2'.

In a parallel circuit with uniform voltage across unequal resistances, branch current is inversely proportional to resistance ($I = V/R$). Unequal resistor values inherently result in differing current flows through each individual parallel branch.
