To align controls in rows and columns like a spreadsheet, with labels across the top, which layout should be used?

The correct answer is: A. Datasheet

A datasheet layout is a type of layout that aligns controls in rows and columns like a spreadsheet, with labels across the top. This type of layout is often used for data entry and analysis, as it makes it easy to see and compare data.

A justified layout is a type of layout that aligns controls to the left and right margins. This type of layout is often used for text-based content, as it makes it easy to read.

A stacked layout is a type of layout that aligns controls vertically, one on top of the other. This type of layout is often used for small controls, as it saves space.

A tabular layout is a type of layout that aligns controls in rows and columns, but does not have labels across the top. This type of layout is often used for content that does not need to be compared or analyzed, as it is not as easy to see and compare data as a datasheet layout.
