Which of the following statement(s) is (are) INCORRECT ?. (A) If `lim_(x->c) f(x) and lim_(x->c) g(x)` both does not exist then `lim_(x->c) f(g(x))` also does not exist.(B) If `lim_(x->c) f(x) and lim_(x->c) g(x)` both does not exist then `lim_(x->c) f'(g(x))` also does not exist.(C) If `lim_(x->c) f(x)` exists and `lim_(x->c) g(x)` does not exist then `lim_(x->c) g(f(x))` does not exist. (D) If `lim_(x->c) f(x) and lim_(x->c) g(x)` both exist then `lim_(x->c) f(g(x)) and lim_(x->c) g(f(x))` also exist.
