STEP 1: Recall what a polynomial is

STEP 2: Recall what are the roots of a poynomial

STEP 3: What is the degree of the polynomial

STEP 4: Pick the statement of the correct choice.

Roots may be real or complex.

Some roots may be complex numbers that have an imaginary part. Complex roots come in pairs.

Since the degree of the given polynomial is 4, the polynomial can have 4 real roots, or 2 real and 2 complex roots or 4 complex roots.

So, option 2 is the correct answer.
