Model Answer
The correct answer is (D) can.
"Can" expresses ability/capability, which fits the context: only we can (have the ability to) save our planet.
Explanation
- Can = ability or capability — the poster urges that humans have the power to save Earth.
- May = permission; shall = formal future/obligation; will = simple future intention — none convey the sense of ability needed here.
- The source passages are grammar/comprehension exercises and do not directly address this question, but standard CBSE grammar rules apply.
