A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

1-4System ManagementModerate

A process may respond to a delivered signal in exactly three ways. Which set is it?

Log it, mask it, or escalate it to the kernelMasking delays delivery; it is not one of the three dispositions.
Queue it, forward it, or return it to senderSignals are not forwarded or returned by a disposition.
Take the default, ignore it, or catch itCorrect · your answerCorrect. Default, ignore, or catch.
Suspend, resume, or restart the process itselfSuspend and resume are default actions of specific signals, not the disposition set.

Correct.

Concept

Signal disposition is per signal and per process: the process either takes what the kernel does by default, opts out, or supplies its own function.

Why C

On delivery a process performs the default action, ignores the signal, or catches it with a programmer-defined handler that runs when the signal arrives.
