Hi , I have one doubt here. had it been {aⁿbⁿ| n>=0 } , here  is also accepted. 

But , for this case don't we require any transition function   

?

Please clarify this doubt.

---

if we add this transition function then also the language remain same .  

---

Yes , that's true . But , I just wanted to know whether it is mandatory to give the blank transition.

---

Not mandatory.

Thank you @Arjun sir :)

thank u :) :) :) :) :)  i was confused between b and d ..got it  now ..

I think giving epsilon transition is required for accepting {aⁿbⁿ| n>=0 }.. D looks more appropriate option here.
