To answer this question, you need to understand the concept of constructors.
Option A) method - This option is incorrect because a method is a block of code that performs a specific task. It is not automatically invoked when an object is created.
Option B) garbage collection - This option is incorrect because garbage collection is the process of automatically reclaiming the memory occupied by objects that are no longer in use. It is not invoked when an object is created.
Option C) finalizer - This option is incorrect because a finalizer is a special method that is automatically called before an object is garbage collected. It is not invoked when an object is created.
Option D) Constructor - This option is correct because a constructor is a special method that is automatically invoked when an object is created. It is used to initialize the state of the object and allocate memory for it.
Option E) none of the above - This option is incorrect because option D, Constructor, is the correct answer.
The correct answer is D) Constructor. This option is correct because a constructor is automatically invoked when an object is created.
