Explanation:

Question 4

In Python, a tuple is defined using parentheses (). A list is defined using square brackets []. Also, a single - element tuple must have a trailing comma (e.g., ('apple',) is a tuple, while ('apple') is just a string in parentheses).

In Python, the == operator is a comparison operator. When you compare 10 == "10", Python evaluates this comparison and returns either True or False. The data type of the result of a comparison operation is bool (boolean).

• A list in Python can have duplicate elements. For example, [1, 2, 2, 3] is a valid list.
• A set in Python cannot have duplicate elements. If you try to create a set like {1, 2, 2, 3}, Python will automatically remove the duplicates and store it as {1, 2, 3}.
• In a dict (dictionary), keys must be unique. If you try to assign a value to an existing key, it will overwrite the previous value associated with that key.

Answer:

A. (1, 2, 3)
