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