In C++ What is the reason for including the following code snippet in the header fileCar.h?#ifndef CAR_H#define CAR_Hclass Car{public:Car();Car (double speed);void start ();void accelerate (double speed);void stop();double get_speed() const;private:double speed1;};#endifTo provide the implementation of the Car classTo define the interface for the Car classTo expose implementation details of the Car class to programmers of otherclassesTo make it possible for other programmers to use Car objects in an aggregation

Programming header files often provide declarations for variables, functions, constants, and other entities that are used in a program but defined in a different source file. It acts as a bridge between various program components, enabling the encapsulation and modularization of code.File extensions like ".h" (for C and C++) or ".hpp" (for C++) are commonly used for header files.The correct reason for including the given code snippet in the header file Car.h is:b. To define the interface for the Car classOptions a, c, and d are incorrect with respect to the given code snippet:a. To provide the implementation of the Car class: Header files generally contain declarations (interface) rather than implementations. Implementations are typically provided in source files (e.g., Car.cpp).c. To expose implementation details of the Car class to programmers of other classes: Header files should not expose implementation details. They should only provide the interface to the class, keeping the implementation details hidden. This promotes encapsulation and reduces dependencies.d. To make it possible for other programmers to use Car objects in an aggregation: The inclusion of the class declaration in the header file enables other programmers to use objects of the Car class, but aggregation is more related to combining objects in a meaningful way, and it is not directly addressed by the given code.Option B. is the correct answer.
