PLEASE HELP!
State whether the following statement is true or false.
Every rational function has at least one asymptote.
Choose the correct answer below.

A.
The statement is true. The denominator of a rational function must have at least one​ zero, so every rational function has at least one vertical asymptote.
B.
The statement is true. Some rational functions do not have vertical​ asymptotes, but every rational function has a horizontal or oblique asymptote.
C.
The statement is false. Some rational functions have a numerator that has a degree two greater than the degree of the​ denominator, and the denominator does not have any zeros.
D.
The statement is false. Sometimes the rational function may be undefined over an interval rather than at specific values.
