A metal wire of resistance $3 \Omega$ is elongated to make a uniform wire of double its previous length. This new wire is now bent and the ends joined to make a circle. If two points on this circle make an angle $60^{\circ}$ at the centre, the equivalent resistance between these two points will be :
Select the correct option:
A
$\frac{5}{3} \Omega$
B
$\frac{5}{2} \Omega$
C
$\frac{7}{2} \Omega$
D
$\frac{12}{5} \Omega$
