The degree of a quadratic polynomial is:
A). 0
B). 1
C). 2
D). 3

Hint: To solve this question we have to tell the degree of a quadratic equation. Any equation which has the highest power equal to two then equations is known as a quadratic equation. In order to find the answer we have to check the option if the degree is matched with the quadratic equation then that is the right answer. And all others are the right answer.

Complete step-by-step solution:
If any equation having the highest power equal to 2 then that equation is known as the quadratic equation. So the degree of the quadratic equation is 2. So according to this option c is the correct answer.
Any equation with the highest degree 0 is known as the constant function so option a is incorrect.
An equation with the highest degree 1 is known as the linear equation. so, option b is incorrect.
An equation with the highest degree 3 is known as the cubic equation. so, option d is also incorrect.

Note: Polynomial: any expression in terms of variables and their coefficient added by the symbols of addition, subtraction, multiplication, and division, and the last thing variables can consist of any value other than negative power is known as a polynomial. In any degree polynomial, it is possible that there is no number of polynomials; it means a polynomial contains any number of the polynomial. Example- \[3{x^3} + 4xyz + 8{y^2}z = 0\] is a three degree polynomial which contains 3 variables that are \[x,y,z\].
