The answer y(x + 2) (x - 2) is correct as it represents the least common factor (LCF) of the given options.

To understand why this is the case, it's essential to recognize that:

    
• The LCF is a polynomial that can evenly divide all the polynomials in the set.
    
• The factor y(x + 2)(x - 2) includes all the terms necessary to cover each option effectively without leaving any terms behind, while the others do not.

Thus, it combines the necessary factors in a way that it can be used in algebraic operations like simplification or solving equations related to these polynomials.
