A piece of uniform resistance wire is bent into a circle and the two ends soldered together. A and B are the end points of a diameter and C is a point equidistant from them. If the resistance between A and C is 1.5\[\Omega \], then the resistance between A and B will be

A)  \[1.5\pi \,\,\Omega \]     

B)  \[3\pi \,\,\Omega \]

C)  \[1.5\text{ }\Omega \]               

D)  \[3.0\text{ }\Omega \]
