Which data structure allows for efficient retrieval and modification of data elements?

The selection of all of the above is appropriate because each of these data structures—array, stack, and tree—offers unique characteristics that contribute to efficient data retrieval and modification, depending on the context in which they are used.

An array provides efficient access to elements by index, allowing for quick retrieval and modification operations. This characteristic makes arrays suitable for scenarios where frequent access to elements by their position is necessary.

A stack, which operates on a Last In, First Out (LIFO) principle, allows for efficient access and modification of the most recently added elements. Operations like push (adding an element) and pop (removing an element) are performed in constant time, making stacks very efficient for certain applications, such as function call management in programming languages.

A tree, particularly a binary search tree, enables efficient searching, insertion, and deletion of elements. Because trees maintain a hierarchical structure, they can reduce the time complexity of these operations significantly compared to simpler data structures, especially when dealing with sorted data.

Thus, choosing all of the above recognizes that each data structure offers distinct advantages in terms of efficient data handling, making them appropriate choices for various applications in programming and data management.
