Question:

Which of the following statements is true regarding immutable objects in Python?

Options:

    
• A) Lists, sets, and dictionaries are examples of immutable objects.
    
• B) When an immutable object is modified, its memory address remains unchanged.
    
• C) Tuples and strings cannot be modified after they are created.
    
• D) Immutable objects cannot be used as keys in Python dictionaries.

Correct Answer: C) Tuples and strings cannot be modified after they are created.

Detailed Explanation:

    
• Option A is incorrect: Lists, sets, and dictionaries are mutable in Python, meaning their contents can be changed in place without changing their identity.
    
• Option B is incorrect: Immutable objects cannot be altered in place. Any operation that appears to modify an immutable object actually generates a new object with a different memory address (identity).
    
• Option C is correct: Tuples, strings, integers, and floats are immutable types. Once instantiated, their values cannot be altered directly. Any modification results in the creation of a new instance.
    
• Option D is incorrect: Dictionary keys require hashable types, and immutable objects (such as strings, integers, and tuples containing only immutable elements) are commonly used as dictionary keys.
