• D

Explanation

The exhibit shows the directory listings for three different workers (worker1, worker2, and worker3) under the /querywkr/active/13127* path, which indicates active query tasks assigned to 1. Worker1 (worker1) The output does not show any subdirectories or task files (13127t0, 13127t1, etc.), meaning Worker1 is not assigned any tasks. 2. Worker2 (worker2) The output shows one task (13127t1) under /querywkr/active/13127*. The worker has only one assigned task, not two, so options C and D are incorrect. 3. Worker3 (worker3) The output shows two tasks (13127t0 and 13127t1), indicating that Worker3 is processing two tasks for query ID 13127.
