What does extant mean?

The term "extant" refers specifically to something that still exists or is currently in existence. In many contexts, it is used in reference to species, documents, or artifacts that have survived over time and are not lost or extinct. The definition aligns perfectly with the idea of being "still existing and not lost." This distinguishes it from options that suggest a lack of existence or the idea of something being newly created, which do not accurately capture the meaning of "extant." Thus, the choice that states "still existing and not lost" is the correct interpretation of the word.
