Answer:

Option A is correct.

Step-by-step explanation:

We have to find: Polynomial which is difference of two square.

Option A).

x² - 16

It can be written as x

= x² - 4² (since 16 is square of 4)

So, this is correct Option.

Option B).

x² / 16

It can be written as x

= x² / 4² (since 16 is square of 4)

So, this is not correct Option as there is division between them.

Option C).

x² - 8

So, this is not correct Option as 8 is not square of any real number.

Option D).

x² / 8

So, this is not correct Option as there is division operation between them.

Therefore, Option A is correct.
