**Common Data for Questions 71, 72,73:**

In the transistor amplifier circuit shown in the figure below, the transistor has the following parameters:

\[ \beta_{\mathrm{DC}}=60, \mathrm{~V}_{\mathrm{BE}}=0.7 \mathrm{~V}, h_{n^{c}} \longrightarrow \infty, h_{f \times} \longrightarrow \infty\]

The capacitance $\mathrm{C}_{\text {c }}$ can be assumed to be infinite.

In the figure above, the ground has been shown by the symbol $\nabla$

If $\beta_{\mathrm{DC}}$ is increased by $10 \%$, then collector-to-emitter voltage drop

- increases by less than or equal to $10 \%$
- decreases by less than or equal to $10 \%$
- increases by more than $10 \%$
- decreases by more than $10 \%$
