Which of the following accurately describes C++'s view on object initialization and destruction?

  1. Only base class constructors are automatically called

  2. Destructors must be explicitly called for subobjects

  3. Constructors for all subobjects are guaranteed to be called

  4. Initialization of built-in types is automatically provided

The correct answer is: Constructors for all subobjects are guaranteed to be called

In C++, constructors for all subobjects are guaranteed to be called. This means that when an object is created, the constructors for all of its member objects will be called, ensuring complete initialization of the object. The other options, A, B, and D, are incorrect because they do not fully capture the behavior of object initialization and destruction in C++. Option A only mentions base class constructors, but fails to mention the initialization of member objects. Option B suggests that destructors must be explicitly called for subobjects, when in fact they are automatically called when an object is destroyed. Option D specifically mentions built-in types, but does not address the initialization of user-defined objects.
