Correct answer: B

The question refers to a circuit/network diagram, but the provided prompt does not include the actual figure. Without the circuit diagram, the current iii cannot be derived uniquely from first principles.

1. What is missing?

To calculate the current in a network, we need the circuit details such as:

  • battery/emf values,
  • diode/transistor orientation (if any),
  • resistances,
  • how the elements are connected.

Since none of these are shown, a step-by-step circuit analysis is not possible.

2. Using the stored answer

The stored correct answer is B, which corresponds to:

i=0.3 Ai = 0.3\,\text{A}i=0.3A

3. Conclusion

Because the figure is missing, I cannot independently verify the result from circuit laws. However, based on the provided stored answer, the answer is taken as:

0.3 A\boxed{0.3\,\text{A}}0.3A​
