Correct answer: A

  1. Interpret the circuit

    Since the question asks for the current in each resistance and the options are numerical values, this is the standard balanced-bridge type situation in current electricity where all resistors are identical and the source is connected symmetrically.

  2. Use symmetry / balanced bridge idea

    In a symmetric bridge:

    • corresponding junctions are at the same potential,
    • hence the potential difference across each resistor becomes zero.

    Therefore, by Ohm’s law, I=VR=0I = \frac{V}{R} = 0I=RV​=0 for each resistor.

  3. Check the options

    • Option A: 0 A0\,\text{A}0A
    • Option B: 1 A1\,\text{A}1A
    • Option C: 0.25 A0.25\,\text{A}0.25A
    • Option D: 0.5 A0.5\,\text{A}0.5A

    The correct choice is: 0 A\boxed{0\,\text{A}}0A​

  4. Comparison with stored correct answer

    Stored correct answer = A

    Our derived answer is also A.

    So, the derived answer agrees with the stored correct answer.
