Show answer & explanation
Correct answer: C
Each fork() system call duplicates the calling process, doubling the total number of running processes. If a program calls fork() consecutively n times, it generates a total of 2n processes. Here, n = 3, creating 23 = 8 concurrent processes (1 parent + 7 children). Each process executes the printf statement once.
Thus, the correct option is C.
