There is a horizontal film of soap solution. On it a thread is placed in the form of a loop. The film is pierced inside the loop and the thread becomes a circular loop of radius R. If the surface tension of the loop be T, then what will be the tension in the thread [RPET 1996]

• A. \[\pi {{R}^{2}}/T\]             
• B. \[\pi {{R}^{2}}T\]
• C. \[2\pi RT\]                              
• D. \[2RT\]
