The correct sentence that demonstrates proper subject-verb agreement is:
C. where is the students going to plant
However, it contains a grammatical error in plural/singular coherence. The correct form should be "where are the students going to plant."
None of the original options perfectly demonstrate correct subject-verb agreement. The remaining sentences also have issues with subject-verb agreement:
- A: "where is the plants growing" should be "where are the plants growing."
- B: "where are the hookup for the hose" should be "where is the hookup for the hose."
- D: "where can the watering cans stored" should be "where can the watering cans be stored."
