Which of the following is true in case of a forward biased p-n junction diode?

(a) The positive terminal of the battery sucks electrons from the p-region

(b) The positive terminal of the battery injects electrons into the p-region

(c) The negative terminal of the battery sucks electrons from the p-region

(d) None of the above mentioned statements are true

The question was asked in an international level competition.

I need to ask this question from The P-N Junction topic in chapter Diodes of Power Electronics

Right option is (a) The positive terminal of the battery sucks electrons from the p-region

Explanation: The diode is forward biased, positive is connected to p & vice-versa, as such batter provides EMF to drive electrons from n-region to p-region.
