The correct option is

(A) 3x plus 3 over x plus 7.

Step-by-step explanation: We are given to find the simplified form of the following expression :

"5x plus 4 over x plus 7 minus the fraction 2x plus 1 over x plus 7".

The given expression can be written and simplified as follows :

$\dfrac{5x+4}{x+7}-\dfrac{2x+1}{x+7}\\\\\\=\dfrac{(5x+4)-(2x+1)}{x+7}\\\\\\=\dfrac{5x+4-2x-1}{x+7}\\\\\\=\dfrac{3x+3}{x+7}.$

Thus, the required simplified form is

"3x plus 3 over x plus 7".

Option (A) is CORRECT.
