The correct answer is "D. Primary." In ophthalmology, fixation refers to the ability of the eyes to focus on a specific point. The classifications of fixation are central, steady, and maintained.

Central fixation refers to the ability to focus on a specific point within the visual field. Steady fixation is the ability to maintain focus on that point. Maintained fixation involves keeping the eyes focused on the same point over time.

On the other hand, "Primary" is not a classification of fixation in ophthalmology. It is important to understand the classifications of fixation to assess visual function accurately in patients.
