Solution

Breakdown of the Problem

  1. Identify the access modifier in question: protected.
  2. Understand how access modifiers apply when a class is inherited.

Relevant Concepts

  • In object-oriented programming, access modifiers dictate how members (variables and methods) of a class can be accessed.
  • Protected members allow access within the same package and also by subclasses, even if they are in different packages.

Analysis and Detail

When a class member is declared as protected, it is accessible in the following contexts:

  1. Within the class itself.
  2. In any subclass (derived classes) of that class, regardless of whether the subclass is in the same package or a different package.

Thus, when a protected member is inherited by a subclass, it retains its access level.

Verify and Summarize

Considering the options given:

  1. Public member: Incorrect, as protected does not become public.
  2. Protected member: Correct, as a protected member remains protected in the subclass.
  3. Private member: Incorrect, as protected does not become private.
  4. Static member: Incorrect context, as static is an additional property unrelated to access modifiers directly.

Final Answer

A class member declared protected becomes a protected member of the subclass.
