**Answer: **

**Step-by-step explanation:**

A binomial is called **perfect square trinomial **

if is satisfied.

For

a = 49, b = -28 and c = 16,

Thus, is not a **perfect square trinomial.**

For

a = 4, b = -20 and c = 25,

Thus, is a **perfect square trinomial.**

For

a = 25, b = -20 and c = -16,

Thus, is not a **perfect square trinomial.**

For

a = 16, b = -24 and c = -9,

Thus, is not a **perfect square trinomial.**
