In the given C program that involves double pointers, the output depends on how the double pointer is manipulated and the values it points to.

The correct answer, which is "3 3 3," suggests that three separate variables or memory locations were being accessed or modified indirectly through the double pointer, resulting in the same value of 3 being printed for all three instances.

In typical setups where a double pointer is utilized, you might have a pointer pointing to an array or a set of variables. When a standard pointer is assigned to the address of a variable, any modification made through that pointer affects the original variable. If all three pointers in the execution of the program pointed to the same variable initialized to 3, or if the program involved copying the value of 3 into multiple locations, the output would consistently print 3 for each reference made through the double pointer.

This allows for a scenario where through dereferencing the double pointer correctly, the specific original value is maintained across all instances being accessed, leading to "3 3 3" being printed.

The other potential outputs, such as "0 0 0", "3 0 3", and "3 3 0", would require different manipulations of the
