b) It is a binomial with degree 3

#### Explanation:

It has two terms: $\left(- 3 x {y}^{2}\right)$ and $\left(5 {x}^{2} y\right)$ $\rightarrow$ it is a binomial
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The degree of an expression is the largest sum of exponents of variables for any term in the expression.

$- 3 x {y}^{2} = - 3 {x}^{1} {y}^{2}$ has a sum of exponents of variables $= 3$
$5 {x}^{2} y = 5 {x}^{2} {y}^{1}$ also has a sum of exponents of variables $= 3$
$\rightarrow$ the expression has degree $3$
