In ABAP, how is a temporary table defined?

A temporary table in ABAP is defined as an internal table that stores multiple entries in a structured manner. The correct definition shown in the selected choice creates a standard internal table with a specific data type.

When defining it as DATA: lt_temp TYPE TABLE OF string, you are explicitly stating that lt_temp is to be an internal table that can hold multiple elements of type string. This is essential for handling collections of data, allowing dynamic storage and manipulation of records during program execution without persisting them in a database.

Other definitions, while related to data types and structures, do not correctly represent the concept of a temporary table. Using a reference type (as in one of the alternatives) indicates a pointer to a data object rather than an actual collection of data. Similarly, defining it using "LIKE" does not create a table type but rather copies the structure of an existing table, and thus it is not explicitly defining a temporary table. The "HASHED TABLE" type mentioned in another choice is designed for quick access based on a unique key but represents a different manner of organizing data compared to a standard internal table. Thus, the selected answer correctly captures what is required for defining a temporary table in ABAP.
