Which for loop prints data across each row in the following code snippet?

In the context of the question regarding which for loop prints data across each row, the correct choice indicates that the inner for loop is responsible for this function. This is because inner loops are typically designed to iterate through and process elements that correspond to a specific row, handling the details of printing data point by point, while the outer loop manages the broader structure, such as iterating through each row itself.

In many programming scenarios, the outer for loop will iterate over rows (for example, in a two-dimensional array or matrix), while the inner loop will iterate over the individual elements of each row. This means that when the inner loop runs, it accesses and prints all elements within a single row before the outer loop advances to the next row.

Specifying that the inner loop prints data ensures clarity about the data's organization in a grid-like structure, emphasizing that it operates on a smaller scale compared to the outer loop's role. This distinction is crucial for understanding nested loops and their respective functions in programming, particularly in scenarios involving arrays or matrices.
