C#.NET inheritance accessibility — which base-class members are accessible to derived classes? Choose all that apply among: 1) static 2) protected 3) private 4) shared (VB equivalent of static) 5) public

Introduction / Context:
This item tests knowledge of which access modifiers allow a derived class to access base-class members in C#.

Given Data / Assumptions:

• protected members are visible to derived classes.
• public members are visible everywhere, including in derived classes.
• private members are not visible outside the declaring class.
• static (and VB’s shared) describe storage/dispatch, not accessibility by themselves.

Concept / Approach:
Accessibility is determined by access modifiers like public, protected, internal, etc. Whether a member is static or instance is orthogonal to accessibility; a member can be public static or protected static.

Step-by-Step Solution:

Verification / Alternative check:
Create a base with protected and public members and access them from a derived type; attempting to access private will cause a compile error.

Why Other Options Are Wrong:
They include private or confuse static/shared with accessibility.

Common Pitfalls:
Assuming static implies global accessibility. It does not.
