(a) 254

(b) 100

(c) 1000

(d) 500

I have been asked this question in an interview.

I'd like to ask this question from Emitter Feedback Bias in portion Transistor Biasing and Thermal Stabilization of Electronic Devices & Circuits

Best answer
Right choice is (a) 254

Easy explanation: VCC=Vce+IC RC + IE RE

IC=1.27mA

Beta=1.27/0.005=254.
