To use a transistor as an amplifier (a) the emitter base junction is forward biased and the base collector junction is reversed biased (b) no bias voltage is required (c) both junction are forward biased (d) both junction are reverse biased

Answer: (a). For active (amplifying) operation, the emitter-base junction must be forward biased to inject carriers. The collector-base junction must be reverse biased to collect them. So the answer is (a).
