Answer: B

Explanation:

In Python, the distinction between lists and tuples is essential for efficient programming:

Lists:

Mutable (B): This means that once a list is created, its elements can be changed, added, or removed.

Lists are versatile and commonly used when the data is expected to change.

Square Brackets: Lists are defined using square brackets [].

Example:

my_list = [1, 2, 3]

my_list[0] = 10 # Modifying the first element

Tuples:

Immutable (B): Once a tuple is created, it cannot be altered. Tuples are used when a fixed collection of items is needed, providing more integrity to the data.

Parentheses: Tuples are defined using parentheses ().

Example:

my_tuple = (1, 2, 3)

# my_tuple[0] = 10 # This would raise an error because tuples are immutable

Reference: Python Official Documentation: The Python Language Reference provides detailed information on data types like lists and tuples, including their mutability and syntax.

Automation Scripts: In the context of automation, understanding when to use mutable or immutable data structures can significantly impact script performance and reliability.
