Solution

The correct option is B 3
The highest degree amongst the degrees of the different terms of an algebraic expression is called the degree of the expression.
In the expression, $7 x^{2} - 24 x y^{2} + 9 x - 2 y^{2}$ ,
The degree of $7 x^{2}$ is 2,
degree of $- 24 x y^{2}$ is 1 + 2 = 3,
degree of 9x is 1,
and degree of $- 2 y^{2}$ is 2.
So, the highest degree of the expression is 3.
