The answer is B.

Consider the fraction (6 √(5) )/(√(5)).

Both the numerator and denominator, when by themselves, are irrational.

However, when they are divided, they result in the rational number (6 √(5) )/(√(5))=\boxed{6}.

When p,q have the same irrational factor, the irrational factor will be cancelled from the fraction and (possibly) leave a rational number.

Answer: The answer is B.
