A.

Incorrect.

C is right.

To determine the correct answer to this question, we should first understand the purpose of parent-teacher conferences. These conferences typically provide an opportunity for parents or guardians to meet with their child's teacher to discuss the student's academic progress, behavior, and any concerns or questions.

Traditionally, parent-teacher conferences took place between the teacher and the parents or guardians of the student. Therefore, the correct answer would be the mothers or fathers of the student, represented by options B and C.

However, it is important to note that the question states that this participation role is changing, suggesting that there may be a shift in who attends parent-teacher conferences. It is possible that other individuals, such as employers or siblings, are now participating in these conferences as well.

To definitively answer the question, it would be best to consult current research or school policies to determine the specific participation roles in parent-teacher conferences as they may vary depending on the school or educational system.
