AIIMS 2018 Physics Diodes and Circuits MCQ Question

In this scenario, the diode's current being five times that of resistor R₁ implies a specific relationship between the currents and the breakdown voltage of the diode. Given that the breakdown voltage is 6 V, and without additional information about the circuit configuration or values of R₁, it is impossible to calculate a specific resistance value for R. Therefore, option B is correct as it indicates that no valid resistance value can be determined with the provided information. The other options are marked as N/A, reinforcing that they also do not provide a valid answer due to insufficient data.
