Find the quotient of the functions f(x) = x^2 - 16 and g(x) = x + 4, and determine its domain. Which of the following options correctly represents the quotient and its domain?

A) f/g, domain: all real numbers except x = -4
B) f/g, domain: all real numbers except x = 4
C) g/f, domain: all real numbers except x = -4
D) g/f, domain: all real numbers except x = 4
