Vertical asymptotes are at 
where 
is any real number zero of the denominator polynomial. Holes occur when the denominator and numerator have factors in common.
This rational function has two distinct real number zeros in the denominator polynomial (finding them is left as an exercise for the student) and it has no factors in common between the numerator and denominator. Consequently, there are no holes and there are two vertical asymptotes. None of the answers given match this pattern, hence you need an answer E: None of the above.
