In a common emitter transistor amplifier the audio signal voltage across the collector is 3V. The resistance of collector is 3 kΩ. If current gain is 100 and the base resistance is 2kΩ, the voltage and power gain of the amplifier is :

• A. 200 and 1000
• B. 15 and 200
• C. 150 and 15000
• D. 20 and 2000
