Things that do not come from the ground not safe to compost.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. are not safe.
The subject "Things" is plural, so the correct verb form is "are" to match the subject-verb agreement.
The other options ("has not been safe," "is not safe," "be not safe") are either ungrammatical or do not align with the plural subject.
