Why are static initialization order dependencies problematic?

They cause the program to crash at runtime

They result in undefined behavior if initialization order varies across translation units

Static initialization order dependencies are problematic because they lead to undefined behavior if the initialization order varies across translation units. This means that the program can behave unpredictably and produce errors if the order of initializing static variables is different in different parts of the program. The other options are incorrect because A is not always the case, and C and D are not related to the specific issue of static initialization order dependencies.

They slow down program execution

They force all static initializations to happen before main()
