Hi, actually problem is coming up regarding an answer given as in how the voltage signal allowable is this. 8v to -3.4v

Seems like so, but in previous editions also, this exercise has carried on.I can understand your confusion. That problem seems to have incorrect answers.
With a 1mA constant-current emitter current, the transistor has no AC gain since the emitter current cannot change, and thus the collector current also cannot change, so the collector voltage is essentially constant with a change is base voltage (see simulation below).
The only way to get AC amplification is if the emitter is bypassed with a capacitor to ground.
