Which Windows tool is used to view and manage running processes?

Correct answer: Task Manager

Option C is correct because Task Manager is the primary Windows utility for viewing currently running processes, monitoring CPU and memory usage per process, and terminating unresponsive applications. Option A is wrong because Device Manager is used to view and manage hardware devices and their drivers, not running software processes. Option B is wrong because Event Viewer is a log-viewing tool for system, security, and application event logs, not a live process manager. Option D is wrong because the Services console (services.msc) manages Windows background services specifically and does not show all running user-mode processes.
