Concept:The G-20 18th meeting officially adopted a motto that emphasizes global unity, environmental responsibility, and a shared vision for the future.
Explanation:The correct motto is “One Earth, One Family, One Future.” This phrase links the planet (Earth), human solidarity (Family), and a forward-looking goal (Future).
Option B (One Earth, One Nature, One Life) replaces “Family” and “Future” with different words, so it does not match the official motto.
Option C (One World, One Family, One Life) changes “Earth” to “World” and omits “Future.”
Option D (One Earth, One Nature, One Future) keeps Earth and Future but leaves out “Family.”
Only option A contains all three key components: Earth, Family, and Future. Therefore, it is the exact official motto.
Answer:Option A: One Earth, One Family, One Future
