The wire in a heating element has resistance $R$. It breaks and is swapped for another wire. The data for the original wire and the replacement wire are shown: the original wire has length $l$, diameter $d$, resistivity $\rho$; the replacement wire has length $l$, diameter $2d$, resistivity $2\rho$. What is the resistance of the replacement wire?
- A$\frac{R}{4}$
- B$\frac{R}{2}$
- C$R$
- D$2R$
