Best Answer Explained in Below-:

The term "indigenous" refers to people, species, or cultures that are native to a particular region or environment, highlighting their longstanding, original presence in that locale. Conversely, the antonym "alien" describes that which is foreign, not originating from a particular place or context. An "alien" entity is typically one that has been introduced from elsewhere, thereby contrasting sharply with the concepts of local and native associations embodied by "indigenous."

The other options—"international," "remote," and "poor"—do not effectively convey a direct opposition to "indigenous." "International" suggests a global perspective that spans multiple nations, while "remote" describes a location's distance from a center or population, none of which inherently imply foreignness. "Poor" pertains to economic status and does not relate to the idea of origin at all. Thus, "alien" stands out as the most suitable antonym to "indigenous," as it captures the essence of being non-native or foreign in contrast to the characteristics of being original or local.
