A mangrove forests tangled roots provide good hiding places for aquatic organisms. Choose 1 answer: (A) NO CHANGE (B) forest's tangled roots (C) forests' tangled roots (D) forest's tangled root's

To determine the correct answer, we need to analyze the possessive form and pluralization in the sentence. The original sentence is: "A mangrove forests tangled roots provide good hiding places for aquatic organisms." 1. **Identify the subject**: The subject is "mangrove forests." Since "forests" is plural, we need to consider how to express possession correctly. 2. **Possessive forms**: - (A) NO CHANGE: "mangrove forests tangled roots" - This is incorrect because it lacks possession. - (B) "forest's tangled roots" - This is incorrect because it suggests a single forest, not multiple forests. - (C) "forests' tangled roots" - This is correct because it indicates that the tangled roots belong to multiple forests. - (D) "forest's tangled root's" - This is incorrect due to the unnecessary apostrophe at the end, suggesting possession of a singular root. Based on this analysis, the correct answer is: **(C) forests' tangled roots**.
