Answer is B
We can eliminate A as this e-NFA accepts 10
We can eliminate C as Epselon is not in this language which is accepted by above e-NFA
Since Strings generated by language B are {e,0,1,00,01,10,11....}, which contains all strings accepted by e-NFA machine mentioned above.
Question is about what is the actual language accepted by e-NFA aove.
Not like which of these languages accepted by NFA.
