Answer: In the following manner we can describe the C# access modifiers: - Public - The members (Functions & Variables) declared as public can be accessed from anywhere. Private - Private members cannot be accessed from outside the class. This is the default access specifier for a member, i.e if you do not specify an access specifier for a member (variable or function), it will be considered as private. Therefore, string PhoneNumber; is equivalent to private string PhoneNumber; Protected - Protected members can be accessed only from the child classes. Internal - it can be accessed only within the same assembly. Internal Protected - internal protected can be accessed within the same assembly as well as in derived class.
