 V gain   =\left ( \frac{\triangle I_{C}}{\triangle I_{B}} \right )\frac{R_{out}}{R_{in}}

=\left ( \frac{5\times 10^{-3}}{100\times10^{-6}} \right )\times10^{3}

=\frac{1}{20}\times10^{6}=5\times10^{4}

P gain = \left ( \frac{\triangle I_{c}}{\triangle I_{b}} \right )\cdot V gain

              =\left ( \frac{5\times10^{-3}}{100\times 10^{-6}} \right )\cdot 5\times10^{4}

              \Rightarrow 2.5\times10^{6}

\Rightarrow V gain =5\times10^{4}, P gain=2.5\times10^{6}


Option 1)

5\times10^{4},2.5\times10^{6}

Option 2)

5\times 10^{4},5\times10^{5}

Option 3)

5\times10^{4},5\times10^{6}

Option 4)

2.5\times10^{4},2.5\times10^{6}
