Assertion (A) is False:

Assigning a lower priority to the resource holder would only worsen the priority inversion problem. To solve priority inversion, mechanisms like Priority Inheritance Protocol (PIP) or Priority Ceiling Protocol (PCP) are used, where the low-priority process holding the resource temporarily inherits the higher priority of the waiting process, allowing it to complete its critical section faster and release the resource.

Reason (R) is True:

This is the exact definition of Priority Inversion. It occurs when a low-priority task holds a shared resource needed by a high-priority task, causing the high-priority task to wait (effectively being preempted/delayed by medium-priority tasks running instead of the low-priority resource holder).
