Answer:
C.
Step-by-step explanation:
A positive and productive teacher-student relationship is vital for the student for his academic growth as well as social development. Such relations help the student to have a learning desire and tend to achieve success in school then the student who has a non-productive relationship with their teachers.
A non-productive and negative teacher-student relationship can be altered with some efforts. In such relationships, a teacher can build positive and non-productive relationships by trying to have a positive conversation with difficult students in private and know the problems they have. Remind such students of their positive attributes as well. A teacher can go the extra mile by asking their parents that if they can take the student for a coffee or lunch.
From the given options, the incorrect recommendation to improve a non-productive teacher-student relationship would be option C. Holding Ruth for less stringent rules would not be a good idea in a negative relationship as it won't help to make the relationship positive and productive. It may further damage the relationship and make Ruth more stagnant.
Thus option C is correct.
