A conducting bar of length \(L\) is free to slide on two parallel conducting rails as shown in the figure  Two resistors \(R _{1}\) and \(R _{2}\) are connected across the ends of the rails. There is a uniform magnetic field \(\vec{B}\) pointing into the page. An external agent pulls the bar to the left at a constant speed \(v\) The correct statement about the directions of induced currents \(I _{1}\) and \(I _{2}\) flowing through \(R _{1}\) and \(R _{2}\) respectively is

1. A Both \(I _{1}\) and \(I _{2}\) are in anticlockwise direction
2. B Both \(I _{1}\) and \(I _{2}\) are in clockwise direction
3. C \(I _{1}\) is in clockwise direction and \(I _{2}\) is in anticlockwise direction
4. D \(I _{1}\) is in anticlockwise direction and \(I _{2}\) is in clockwise direction
