As the ring has no resistance, the three resistances of 3 R each are in parallel. The equivalent circuit diagram is <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/01e259ed257a7d50e2a3ca21c80236e7-.png" /> Hence, the equivalent resistance between A and B is Re q=R+R=2 R

As the ring has no resistance, the three resistances of $3 R$ each are in parallel. The equivalent circuit diagram is

Hence, the equivalent resistance between $A$ and $B$ is
$R_{e q} = R + R = 2 R$
