Polynomial B

Step-by-step explanation:

We are given 4 different polynomial. We need to choose 4th degree polynomial from given.

Degree is maximum power of x of polynomial.

Option A:

Degree = 5,  False

Number of term = 3 (Trinomial)

Option B:

Degree = 4

Number of term = 3 (Trinomial)

True

Option C:

Degree = 4

Number of term = 4 (Not Trinomial)

False

Option D:

Degree = 5

Number of term = 3 (Trinomial)

False

Hence, Polynomial B is correct whose degree 4 and number of term 3.
