Concept — In a sentence-rearrangement item the fixed opening fragment creates a grammatical slot, and every remaining part is placed by the dependency its own form demands: a linking verb such as “is becoming” must be completed by a noun phrase; a causal phrase beginning “due to” attaches to the statement whose reason it gives; a place adverbial stays beside the noun or action it modifies; a relative clause beginning “that” attaches to its head noun; and an agent phrase beginning “by” attaches to the action noun that names what is done. Sequence follows grammatical dependency, not topical similarity.

Application to this sentence:

1. The opener “Climate change is becoming” ends in a linking verb, so the part after it must be a noun phrase; of the five parts, “a serious global concern” is the noun phrase, so it fills that slot — part B.

2. “Due to its widespread impact on the environment” supplies the reason for that concern, and a causal phrase follows the statement it explains — B then D.

3. “Across the world” is a place adverbial extending “impact on the environment”, so it stays beside what it modifies — D then E.

4. “That requires urgent and collective action” is a relative clause whose head noun is “concern”; it is attached once the description of that concern is complete — E then A.

5. “By governments, industries, and individuals” names the agents of “action”, so the agent phrase must follow the action noun it belongs to — A then C.

Result — 1 → B → D → E → A → C, that is BDEAC: “Climate change is becoming a serious global concern due to its widespread impact on the environment across the world that requires urgent and collective action by governments, industries, and individuals.”

Cross-check — Test every rival start against the opener: “Climate change is becoming that requires urgent and collective action”, “Climate change is becoming by governments, industries, and individuals” and “Climate change is becoming due to its widespread impact on the environment” all leave the linking verb without the noun complement it needs, while “Climate change is becoming across the world” supplies only an adverbial. The sequence can therefore begin only with the noun phrase, and since “by governments, industries, and individuals” can attach to no noun except “action”, it has to come last — which fixes the order as BDEAC.
