$\large\boxed{A.)\ 2\sqrt5}$

Step-by-step explanation:

The Pythagorean theorem:

leg^2+leg^2=hypotenuse^2

We have

$\leg=2\\leg=4\\hypotenuse=x$

Substitute:

$x^2=2^2+4^2\\\\x^2=4+16\\\\x^2=20\to x=\sqrt{20}\\\\x=\sqrt{4\cdot5}\\\\x=\sqrt4\cdot\sqrt5\\\\x=2\sqrt5$

$\cfrac{\textit{sale price}}{\textit{original price}}=\cfrac{3}{4}\implies \cfrac{\textit{sale price}}{64}=\cfrac{3}{4}$

solve for "sale price"
