The graph between the input voltage $\left(\mathrm{V}_{\mathrm{i}}\right)$ and the output voltage $\left(\mathrm{V}_{\mathrm{o}}\right)$ of a transistor connected in common emitter configuration is shown in the figure. The active, saturation and cutoff regions of the transistor are respectively

• A

  I,II and III
• Correct answer
  B

  II,III and I
• C

  I,III and II
• D

  III,I and II

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