In the circuit shown below during the negative cycle, the input signal—

1. Q₁ is cut-ff
2. Q₂ is cut-off
3. Both Q₁ and Q₂ are cut-off
4. Both Q₁ and Q₂ are conducting

Correct Option: B

The given circuit (i.e., fig)
From given circuit, we observe that transistor Q₁ is pnp type while Q₂ is npn type. So, during the negative cycle of the input signal, transistor Q₁ will conduct while Q₂ will not conduct i.e., Q₂ is cut-off mode. Hence alternative (B) is the correct choice.
