In Scenario 1, a block of mass \( M \) is suspended at rest from an ideal string attached to a fixed horizontal beam. In Scenario 2, the same block is suspended from an identical string that is wrapped around a uniform disk-shaped pulley of mass \( M \) and radius \( R \). The pulley is mounted on a horizontal, frictionless axle. The block in Scenario 2 is released from rest and allowed to accelerate downward as the pulley rotates. Let \( T_1 \) be the tension in the string in Scenario 1 and \( T_2 \) be the tension in the string in Scenario 2. Which of the following correctly compares the tensions and provides a valid justification?
