Step 1
: Understand the definition of a 2D list and its elements

A 2D list is a list of lists, where each element can be a list itself. In other words, it is a table-like data structure with rows and columns. An element in a 2D list refers to the individual items contained within the nested lists.

Step 2
: Examine the 2D list structure

Here, the 2D list $L$ has three elements, each being a sub-list: $[1, 2, 3]$, $[4, 5, 6]$, and $[7, 8, 9]$.
Consider a 2D list like this: L = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

Final Answer

In this example, the elements of the 2D list $L$ are the sub-lists $[1, 2, 3]$, $[4, 5, 6]$, and $[7, 8, 9]$, which consist of individual integers.
