Answer:

Option A.

Explanation:

The given expression is

According to the reflexive property of equality, all values are equal to itself.

a = a

where, a be any real number.

Using the reflexive property we can say that

-25=-25

It means -25 is equal or equivalent to -25.

Therefore, the correct option is A.

Note: If the given expression is
√(-25) , then

√(-25)=√(25)√(-1)
$[\because √(ab)=√(a)\sqrt {b}]$

√(-25)=5i
$[\because √(-1)=i]$

Then the correct option is B.
