Re-arrange the following phrases in the correct sequence to form a meaningful sentence.

(A) created by human
(B) collective cultural heritage
(C) all languages
(D) communities are our

The correct option is (C), (A), (D), (B).

To arrange the given phrases into a meaningful and grammatically correct sentence, we can analyze the grammatical role of each phrase:
- (C) "all languages" acts as the subject of our sentence.
- (A) "created by human" is a participial phrase modifying the noun phrase "all languages", identifying who made them. Together, "all languages created by human" forms the complete subject.
- (D) "communities are our" contains the linking verb "are" which connects the subject to the subject complement, followed by the possessive adjective "our".
- (B) "collective cultural heritage" is the noun phrase functioning as the subject complement, completing the description of what languages are.

Putting these components in the sequence (C) → (A) → (D) → (B) yields:
"All languages created by human communities are our collective cultural heritage."

This forms a coherent, grammatically correct sentence, confirming that the sequence (C), (A), (D), (B) is the correct rearrangement.
