The correct option is (B) [tex]16x^2 + 8x + 1[/tex]

Explanation:
Add all the boxes:
There are 16 (x^2) boxes;
There are 8 (x) boxes;
And the constants = 1

So it becomes:
[tex]16x^2 + 8x + 1[/tex]

And the product is (4x+1)(4x+1)
4x(4x+1) + 1(4x+1)
16x^2 + 4x + 4x + 1
[tex]16x^2 + 8x + 1[/tex] (Same)
