A metal wire X has a constant diameter and resistance $R$. Another wire, Y, is also made from the same metal and has a constant diameter. The cross-sectional area of Y is twice that of X, and the length of Y is half that of X. What is the resistance of Y?
- A$\frac{R}{4}$
- B$\frac{R}{2}$
- C$R$
- D$4R$
