Difficulty: Easy
Correct Answer: 2, 4
Explanation:
Introduction / Context:This question targets the fundamentals of object instances in C#. Objects have state (fields) and behavior (methods). States vary per instance; behavior is defined once in the type and is callable on each instance.
Given Data / Assumptions:
Concept / Approach:Each object holds its own copy of instance fields, so two objects can hold different values. Methods are defined on the type and are invoked with a this reference; conceptually each object “has” those behaviors, though the implementation is a single method body shared by all instances.
Step-by-Step Solution:
(1) False — objects can have different field values.(2) True — they may be same or different depending on assignments.(3) False — not controlled by IDE settings.(4) True — conceptually, every object exposes instance behavior and owns its own data.(5) Implementation detail: yes, method code is shared, but the better paired truth here is (2) and (4) as per conceptual MCQ framing.Verification / Alternative check:Create two Sample objects, set different field values; methods act on each object’s this.
Why Other Options Are Wrong:(1) and (3) are plainly incorrect; (5) alone without (2) omits the crucial property of per-object data.
Common Pitfalls:Confusing the single method implementation with per-object behavior; the important takeaway is that objects don’t share instance data.
Final Answer:2, 4
