1. True, Yes it can but only if the system is a multi-core system, otherwise parallelism is not possible in the case of uni-core systems concurrent execution will be done by doing context switching.

      B. True. Yes, it can wait especially in the case of uni-core it has no other option than waiting.

      C.False. It can be created directly by Kernel.

      D. False. Most of the time child processes are loaded with the parent's program.

@Abhrajyoti00 please check if there is anything wrong.

Answer 1

Answer: Option A,B

Parent process can execute parallely with children. They can also execute after the children. So they can wait until some or all of its children have terminated.

Child process can be the duplicate of parent process or can be loaded with program other than parent program.

@Abhrajyoti00 Just to be sure, the child process can be loaded with some other program that is not the parent program, it is done with the help of EXEC right?
