Answer: D

Explanation:

The expression for the statement that is given is (m² + n²) - 2mn

The expression given is that twice the product of m and n is decreased by the square of the sum of m and n. This will be written as:

= [2 × (m × n)] - (m + n)²

= 2mn - (m² + n²)

= (m² + n²) - 2mn

In conclusion, the correct option is D.
