so... it has degree of 7, so based on the fundamental theorem of algebra....it can have at most 7 solutions
now.. you have −4, −4i, 2i <--- there are two complex ones there
-4i or 0-4i and 2i or 0+2i
now.. bear in mind that, complex solutions never come all by their lonesome, they come with their sister, the conjugate
thus, that means 0-4i comes with 0+4i and 0+2i comes with 0-2i
that makes only 5 roots though
that simply means that, the -4 one, has a multiplicity of 3
as far as the B) and C) sections, check Descartes Rule of Signs

A polynomial is defined as an expression which is composed of variables, constants and exponents, that are combined using the mathematical operations such as addition, subtraction, multiplication and division
R(x) = −4 −4i, 2i
What is a polynomial with example?
Polynomials are sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer.
For example, 3x+2x-5 is a polynomial. Introduction to polynomials. This video covers common terminology like terms, degree, standard form, monomial, binomial and trinomial.
