How can the loading between two stages be reduced?
Answer: C
A follower presents a high impedance to the first stage and a low one to the second, so neither loads the other - impedance transformation at the cost of no voltage gain. A larger capacitor extends the low-frequency response instead, and reducing the collector resistor would lower the gain further rather than help. Inserting a stage whose only job is impedance is worthwhile precisely when the interface, rather than the gain, is the problem. Checking the units of each quantity catches a wrong formula before the arithmetic begins. Checking the units of each quantity catches a wrong formula before the arithmetic begins.
