c. 4x+5y

step-by-step explanation:

lets start by factorizing the expression 16x²+40xy+25y²

consider the expression ax²+bx+c

during factorization, two numbers picked should add up to b while the product should be=ac

we find two numbers that when added give 40 and when multiplied = 16×25=400

these numbers are 20 and 20

therefore the expression will be broken into:

16x²+20xy+20xy+25y²

4x(4x+5y)+5y(4x+5y)

(4x+5y)(4x+5y)

the expression is a perfect square.
