Best Answer Explained in Below-:

The word "extant" refers to something that currently exists or is still in existence, particularly in the context of species, documents, or artifacts. To choose an opposite, we must look for a word that conveys the idea of absence or non-existence. Among the given options, "lost" (D) stands out as the most fitting antonym.

"Existing" (A) holds a similar meaning to "extant," as both refer to presence or currently being. "Dynamic" (B) implies activity or change, not negating existence but rather focusing on the state of being. "Fashionable" (C) pertains to trends and style, which is unrelated to existence per se.

In contrast, "lost" indicates that something is no longer present or has been eradicated, making it directly opposite to "extant." For example, when discussing a lost species, it means that there are no surviving representatives left, contrasting sharply with the concept of extant species that still thrive. Therefore, "lost" aptly captures the opposite of "extant."
