Answer:
Implementation file
Explanation:
In popular object oriented programming languages like C/C++, The implementation file (source file) of a class is used to hold the code implementaion of the method(s) of the class, this is helpful for seperating interface and method implementation. When this seperation exists, header files will be used to declare all the methods and fields of the class.
In this way, the implementaion file will hold the actual source code of the methods that are declared in the header file and will have a line to include its associated header file. A major advantage of seperating code in this way is the enhancement of better code organization and code re-use

Answer:it has high coupling
Explanation: Coupling is the property in the field of computer program that is defined as the functions ,data and codes of the program are dependent on each other and cannot be changed independently if requires. Thus,high amount of coupling is not considered as good factor due to high interdependence. Loose coupling can be still permitted.
Other options are correct because name of the class should reflect the purpose and well defined responsibilities should be present, modeling of certain component and high cohesion means keeping similar functions togather is also required. So, the only bad factor is high coupling
