Question:
Degree of the zero polynomial is
(a) 0
(b) 1
(c) any natural number
(d) not defined
Solution:
(d) The degree of zero polynomial is not defined, because in zero polynomial, the coefficient of any variable is zero i.e., $\mathrm{Ox}^{2}$ or $\mathrm{Ox}^{5}$, etc.
Hence, we cannot exactly determine the degree of variable.
