In a common-emitter transistor amplifier, the audio signal voltage across the collector is $\mathrm{3\; V.}$ The resistance of collector is $3 \mathrm{k\Omega }$. If current gain is $100$ and the base resistance is $2 \mathrm{k\Omega }$, the voltage and power gain of the amplifier is

• A

  $200$ and $1000$
• B

  $15$ and $200$
• Correct answer
  C

  $150$ and $15000$
• D

  $20$ and $2000$

Hence, the correct answer is option: 'C'.
