Final answer:
While the provided sentences contain mistakes, the concept of subject-verb agreement requires matching the verb to the plurality of the subject, with special rules for compound subjects, subjects joined by 'or' or 'nor', intervening words, and inverted sentence structures. The correct option is C) "Mocs, peace and love is achievable for everyone."
Step-by-step explanation:
The sentence with proper subject-verb agreement is not clearly presented among options (A), (B), (C), or (D) as some contain typos or nonsensical phrases. In general, subject-verb agreement rules dictate that when a compound subject is joined by 'and', a plural verb is used, except when the compound subject forms a single entity, then a singular verb is needed.
Conversely, when joined by 'or' or 'nor', the verb agrees with the closest subject element. When other words come between a subject and verb, or when the subject follows the verb, the verb must still agree with the actual subject.
Ignoring typos, the option closest to demonstrating correct subject-verb agreement could suggest that multiple subjects joined by 'and', such as 'Missouri' and 'finds', would necessitate a plural verb to correct to 'Missouri and finds are states along the Mississippi River'.
The sentence that has proper subject-verb agreement is (C) "Mocs, peace and love is achievable for everyone."
When the subjects are joined by "and" in a list, they are considered compound subjects and take a plural verb. However, in this sentence, the subjects "mocs, peace, and love" are treated as a single idea or unit, so the verb "is" is singular.
The correct option is C) "Mocs, peace and love is achievable for everyone."
