D
Question:-
Option (A)
causal
Option (B)
not-causal
Option (C)
both sided
Option (D)
not-possible
Correct Option:
B
Question Solution:
Because number of zero is more than pole, therefore when you find transfer function, Numerator. Power will higher than denominator and such transfer function is not realizable.
