Question

In the figure, given that $\mathrm{V}_{\mathrm{BB}}$ supply can vary from 0 to $5.0 \mathrm{~V}, \mathrm{~V}_{\mathrm{CC}}=5 \mathrm{~V}, \beta_{\mathrm{dc}}=200, \mathrm{R}_{\mathrm{B}}=100 \mathrm{~K} \Omega, \mathrm{R}_{\mathrm{C}}=1 \mathrm{~K} \Omega$ and $\mathrm{V}_{\mathrm{BE}}=1.0 \mathrm{~V}$. The minimum base current and the input voltage at which the transistor will go to saturation, will be respectively

Select the correct option:

$25 \mu \mathrm{~A}$ and 3.5 V

$20 \mu \mathrm{~A}$ and 2.8 V

$25 \mu \mathrm{~A}$ and 2.8 V

$20 \mu \mathrm{~A}$ and 3.5 V
