Well it's not really a matter of which is "best", one is right and the others are wrong :)
is an <em>irrational</em> number, meaning that it can't be expressed with a fraction between integers: in other words, there doesn't exist two integers
such that
This is why option B is wrong. Also, imaginary numbers (option C) are complex numbers with no real part. Since
is not imaginary. Finally, irrational numbers are real numbers, so option D is wrong as well.

Answer:
Step-by-step explanation:
So here we have a 45-45-90 triangle.
This a special right triangle were the sides across from the 45 degree angles can be considered x, while the hypotenuse is two square roots of x.
Here since we have the sides across from the 45 degree angle we can conclude that
So if we wanted the hypotenuse we would just plug in this value of x like so:
Therefore the hypotenuse is 18.
