Find and simplify the expression: f(x) = x^2 - 11f(5+h) - f(5)f(5+h) - f(5).

Which of the following is the correct expression?

A) f(x) = x^2 - 11f(5+h) - f(5)f(5+h) - f(5)
B) f(x) = x^2 - 11f(5+h) - f(5)f(5+h) + f(5)
C) f(x) = x^2 - 11f(5+h) - f(5)f(5+h) + f(5)
D) f(x) = x^2 - 11f(5+h) + f(5)f(5+h) - f(5)
