Show answer & explanation
Correct answer: D
Standard operating system models define two primary behaviors for parent processes after creating children. First, the parent may continue execution concurrently with its children. Second, the parent might block and wait until specific or all children terminate. Both scenarios are valid mechanisms in process management theory.
