The series of full f/stops represents a standardized set of aperture values used in photography to control the amount of light entering the camera. Each value in the sequence halves or doubles the amount of light compared to the previous stop, making it easier for photographers to calculate exposure.

The correct answer includes the full stops: 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, and 32. These values follow a specific doubling and halving pattern, which is essential for achieving correct exposure in different lighting conditions. Understanding this sequence helps photographers in choosing the appropriate aperture settings to achieve the desired depth of field and exposure.

Other options contain incorrect f/stop values that either do not follow the standard full-stop increments or lack the complete range needed for effective exposure control in photography. For example, the values provided in the other choices do not include the complete set that covers the standard apertures, thus limiting a photographer's ability to manage exposure effectively across different lighting scenarios.
