Answer 1

The correct answer is (d) ignore the signal, terminate and suspend the process

For explanation: How a process responds to a signal depends on how things are set up in the program representing the process. However, there are mainly three actions that a program can take upon receiving a signal i.e. ignore the signal and continue execution normally, terminate the process, suspend (stop) the program.
