Solution

The correct option is B $2 x + 5$
A polynomial whose degree is equal to 1 is called a linear polynomial.

The degree of a polynomial is the highest power of the variable in the polynomial.

The degree of the polynomial
$4 x^{4} + 5 x^{3} + 2 x^{2} + 9 x + 6 is 4.$

The degree of the polynomial
$2 x + 5 is 1.$

The degree of the polynomial
$2 x^{2} + 9 x + 6 is 2.$

The degree of the polynomial
$5 x^{3} + 2 x^{2} + 9 x + 6 is 3.$
