I had this question as well, the correct answer is D.
Explanation:
A class member function that automatically initializes the data members of a class is called a constructor.
<h3>What do you mean by constructor?</h3>
- In object-oriented programming, a constructor is a particular method of a class or structure that initializes a newly formed object of that kind. The constructor is always invoked when an object is created.
- Main obj = new Main(); In this case, the Main() constructor is invoked when the object is created. Additionally, the name variable's value is initialized. As a result, the program prints Programiz as the value of the name variables.
- The name of the constructor frequently matches that of the declaring class. They must initialize the object's data members and establish the class invariant, failing if the invariant is incorrect. A well-written constructor's outcome is an object in a usable state.
- When an object of a class is created in C++, the member functions called constructors are called. In C++, constructors fall into one of three categories: default, parameterized, or copy.

Answer:
Given:
Cold water faucet fills the sink in 4 minutes.
Both faucets fills the sink in 3 minutes.
Let us assume that "t" be the time it takes hot water faucet in order to fill the sink.
Therefore;
<em>Rate for hot water faucet fills the sink =
=
</em>
<em>Rate at which cold water faucet fills the sink =
=
</em>
When both faucets are used , the rate at which they fill the sink is given as :
<em>
+
=
</em>
On solving the above equation, we get :
<em>
</em>
<em>∴
</em>
<em>Therefore, it takes 12 minutes for the hot water faucet to fill the sink.</em>
