<h2>Answer:</h2>

Option: C is the correct answer.

C.   Is a difference of squares: (y + 5)(y − 5).

<h2>Step-by-step explanation:</h2>

We are given a polynomial expression in terms of the variable y as follows:

                        y^2-25

Now this expression could also be written as:

y^2-25=y^2-5^2

This means that the expression is a difference of squares.

Also, we know that:

a^2-b^2=(a+b)(a-b)

Here,

a=y\ and\ b=5

Hence,

y^2-25=(y+5)(y-5)
