Best answer
The correct option is (a) True

Best explanation: When the p-side of a semiconductor diode is connected to the positive terminal of the battery and the n-side to the negative terminal, the diode is said to be forward biased. A semiconductor laser is essentially a semiconductor diode, where the active medium is the forward biased p-n junction.
