The voltage gain and the current amplification factor of a transistor in common emitter configuration are 300 and 60 respectively. If the collector resistance is $5 \mathrm{k} \Omega$, then the base resistance is

• A

  $5 \mathrm{k} \Omega$
• B

  $25 \mathrm{k} \Omega$
• C

  $2 \mathrm{k} \Omega$
• Correct answer
  D

  $1 \mathrm{k} \Omega$

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