Which of the following is true about this pointer?a)It is passed as a ...
The ‘this’ pointer is passed as a hidden argument to all non-static member function calls and is available as a local variable within the body of all non-static functions. ‘this’ pointer is a constant pointer that holds the memory address of the current object. ‘this’ pointer is not available in static member functions as static member functions can be called without any object (with class name).

Passing of Pointers in Function Calls
In C programming language, pointers are often used to pass values between functions. They are passed as arguments to functions to allow the function to access and modify the original data. However, there are some nuances to how pointers are passed in function calls.
Hidden Arguments in Function Calls
When a function is called in C, the arguments passed to the function are evaluated and copied into the function's parameter variables. However, there is also a hidden argument that is passed to the function that is not explicitly specified in the function call.
This hidden argument is a pointer to the current object or current instance of the class. It is used in object-oriented programming languages to allow methods to access instance variables and other instance-specific data. However, in C, this hidden argument is used for a different purpose.
Passing Pointers as Hidden Arguments
In C, when a non-static function is called, the hidden argument passed to the function is a pointer to the object that the function is being called on. This allows the function to access and modify the object's data.
However, when a static function is called, there is no hidden argument passed to the function. Static functions do not have access to instance variables, so there is no need to pass a hidden argument.
Answer
The correct answer to the question is option B: It is passed as a hidden argument to all non-static function calls. When a non-static function is called, a hidden argument is passed to the function that is a pointer to the object that the function is being called on. This allows the function to access and modify the object's data.

However, when a static function is called, there is no hidden argument passed to the function. Static functions do not have access to instance variables, so there is no need to pass a hidden argument.
Answer
The correct answer to the question is option B: It is passed as a hidden argument to all non-static function calls. When a non-static function is called, a hidden argument is passed to the function that is a pointer to the object that the function is being called on. This allows the function to access and modify the object's data.
