Question

question: 3
which of the following data structures is immutable?
○ tuple

An immutable data structure cannot be modified after creation. Tuples in programming (e.g., Python) are immutable—their elements cannot be changed, added, or removed once defined. Lists (including 2D lists) and dictionaries are mutable, as their contents can be altered post-creation.

Tuple
