How is 'latent' best described?

The term 'latent' is best described as being present but not active or visible. In various contexts, such as psychology, medicine, or even general usage, 'latent' refers to qualities, conditions, or states that exist but are not currently manifested or evident. For example, a latent infection may exist in the body without showing any symptoms, or latent talents may be inherent abilities that an individual has not yet expressed or developed.

This understanding aligns with the nature of the word, highlighting that while something may not be overtly apparent at the moment, it is still there beneath the surface and has the potential to emerge or become active under certain conditions. In contrast, the other options describe different states—active, fleeting, or persistent—that do not accurately capture the essence of being 'latent.'
