Solution

The correct option is B $15$
The degree of a polynomial is the highest degree of its monomials (individual terms) with non-zero coefficients. The degree of a term is the sum of the exponents of the variables that appear in it, and thus is a non-negative integer.
Degree of non-zero constant polynomial is zero.
Hence, degree of $15$ is $0$ .
