Select the most appropriate option to fill in blank number 3.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. communities.
The most appropriate word to fill is "communities," as it refers to groups of people living in the same area or sharing a common environment.
This term accurately captures the collective aspect of people being affected by environmental changes such as rising sea levels, which may force entire communities to move.
The other options—"mobes" (not a standard word), "people" (too general), and "conditions" (refers to circumstances)—do not convey the specific collective nature implied by "communities."
