(b) (2 pts) When the process is suspended and a SIGUSR2 signal is sent to the process, how does the process react? (A): terminated, (B): resume, (C): no action, or (D) Add SIGUSR2 to the signal mask.
#428888
(c) (2 pts) What's the signal mask when SIGUSR2 is caught by the process: (A) SIGUSR1and SIGUSR2, (B) SIGUSR1, (C) SIGINT and SIGUSR2, and (D) Empty.
