Interrupt manager belongs to which section of interrupt*SoftwareNone of thesePollingHardware

The interrupt manager mainly belongs to the "Software" section of interrupt handling. It is responsible for managing and controlling the way in which the CPU responds to interrupts.

When an interrupt occurs, the interrupt manager ensures that the CPU can handle this request effectively without disrupting ongoing processes unduly. This involves prioritizing various interrupts, saving the state of the running processes, and deciding how to manage multiple interrupts that may occur simultaneously.

In contrast, "Polling" refers to a method where the CPU actively checks the status of an external device to find out if it needs attention, which is less efficient compared to interrupts. On the other hand, "Hardware" refers to the physical components that generate interrupts rather than the management or processing of those interrupts. Therefore, the classification of the interrupt manager under "Software" is appropriate, as it is part of the system's software architecture that facilitates the proper execution of interrupt-driven operations.
