Model Answer
(B) to preserve
Explanation
The infinitive of purpose ("to + base verb") is correct here — "to preserve our world" means "in order to preserve." Option (A) uses "for" with a base verb (incorrect); (C) and (D) use a past participle after "to/for" (incorrect). "For" requires a noun, not a verb.
