Solution

The correct option is B 5
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.

Now, (x32)(x2+11)
=x5+11x32x222

Here, x5 is the monomial with highest power.
So, degree =5

Hence, B is correct.
