Consider the common-collector amplifier in the figure (bias circuitry ensures that the transistor operates in forward active region, but has been omitted for simplicity). Let I${}_C$ be the collector current, V${}_{BE}$ be the base-emitter voltage and V${}_T$ by the thermal voltage. Also, 𝑔${}_{\text{m}}$ and 𝑟${}_{\text{o}}$ are the small-signal transconductance and output resistance of the transistor, respectively. Which one of the following conditions ensures a nearly constant small-signal voltage gain for a wide range of values of R${}_E$?

In the circuit shown, the PNP transistor has |𝑉${}_{BE}$ |= 0.7 V and β = 50. Assume that R${}_B$ = 100 kΩ. For V₀ to be 5 V, the value of R${}_C$ (in kΩ) is ______
