A wire 100\[cm\] long and 2.0\[mm\] diameter has a resistance of 0.7 ohm, the electrical resistivity of the material is

• A.                    \[4.4\times {{10}^{-6}}ohm\times m\]
• B.                                      \[2.2\times {{10}^{-6}}ohm\times m\]
• C.                    \[1.1\times {{10}^{-6}}ohm\times m\]                 
• D.            \[0.22\times {{10}^{-6}}ohm\times m\]
