Which of the following are roadblocks to mutual appreciation between parents and teachers?

A) Parents don't take preschool teachers seriously
B) Teachers don't want to hear what parents have to say
C) Competition, resentment, savior complex
D) Resentment, jealousy, money matters

Competition, resentment, and savior complex can all be roadblocks to mutual appreciation between parents and teachers. This may be due to differences in expectations, communication styles, and misunderstandings about roles and responsibilities. It is important for both parents and teachers to recognize and address these roadblocks in order to build strong and positive relationships that benefit the child's overall development. Options A and B are one-sided and do not address the possible roadblocks from both sides, while option D primarily focuses on financial matters which may not be the main concern for all parents and teachers.
