Increase in collector emitter voltage from 5V to 8V causes increase in collector current from 5mA to 5.3mA. Determine the dynamic output resistance.

(a) 20kΩ

(b) 10kΩ

(c) 50kΩ

(d) 60kΩ

I got this question during an internship interview.

My doubt is from The Common Collector Configuration in portion Transistor Characteristics of Electronic Devices & Circuits
