To solve this question, the user needs to have a basic understanding of object-oriented programming and the concept of constructors.

A constructor is a special method that is called when an object of a class is created. It is used to initialize the data members of the class. The number of constructors that a class can have depends on the programming language being used and the requirements of the developer.

Now, let's go through each option and explain why it is right or wrong:

A. 1: This option is incorrect because a class can have more than one constructor. In fact, many programming languages allow for the creation of multiple constructors with different parameter lists, which can be used to create objects of the class in different ways.

B. 3: This option is incorrect because the number of constructors that a class can have is not fixed. The actual number of constructors that can be defined for a class depends on the language and requirements of the developer.

C. All of the above: This option is also incorrect because option B is incorrect and option C cannot be correct if any of the options are incorrect.

D. 2: This option is incorrect because a class can have more than two constructors. As mentioned earlier, the number of constructors that a class can have depends on the programming language and the requirements of the developer.

Therefore, the correct answer is:

The Answer is: C
