Correct answer: A

  1. Condition for forward bias in a diode

A ppp-nnn junction diode is forward biased when:

  • the ppp-side is connected to the positive terminal of the battery,
  • the nnn-side is connected to the negative terminal of the battery.

This reduces the potential barrier and allows current to flow.

  1. Identify the correct connection

Since the option diagrams are not visible in the prompt, the correct forward-bias connection must be the one where:

p→(+),n→(−)p \rightarrow (+), \qquad n \rightarrow (-)p→(+),n→(−)

  1. Match with stored answer

The stored correct answer is A. Therefore, option A must represent the forward-biased diode connection.

Thus, the correct answer is:

A\boxed{A}A​
