Detailed Solution

Given, a polynomial

13 + 11 x + 12 x^{3} + 3 x^{2} .

We need to find the degree of the polynomial.
The exponent of a polynomial's variable determines a term's degree.
Rearranging the terms,

13 + 11 x + 12 x^{3} + 3 x^{2} = 12 x^{3} + 3 x^{2} + 11 x + 13

The highest exponent of

x

is 3.

∴

Degree of the polynomial =3.
Hence, the correct option is 3.
