When a local static object's constructor is executed?

At program startup
Before the function containing it is first called
After the function containing it returns for the first time
Immediately when the function containing it is defined

The correct answer is: Before the function containing it is first called

Local static objects are objects declared inside a function with the keyword "static". These objects are automatically initialized before any other code is run, but their constructor is only executed when the function containing them is first called. Therefore, options A, C, and D are incorrect because they all refer to a different timing for the constructor's execution. For option A, the program has already started running before the function is called, so the constructor has already been executed. For option C, the function has already returned for the first time, so the constructor cannot be executed. For option D, the function containing the object is not executed until it is called, so the constructor cannot be executed immediately when it is defined.
