Solution

The correct options are
A $x^{3}$
C $0 x^{4} + 4 x^{3} + 4$
D $y^{3} + 2 x$
Degree of a polynomial is the highest of the sum of the exponents of the variables in each term.

Here, we have to find polynomials with degree 3.

1. $x^{3}$
Degree = 3

2. $3 x + x^{2} = x^{2} + 3 x$
Degree = 2

3. $0 x^{4} + 4 x^{3} + 4 = 4 x^{3} + 4$
Degree = 3

4. $y^{3} + 2 x$
Degree = 3
