The correct answer is C. Superstitions.
A teacher should be patient and tolerant, have a sweet, polite, and clear voice, and good communication skills. Superstitions are not necessary for a teacher to be effective.
Patience and tolerance are important qualities for a teacher because they allow the teacher to deal with the challenges of teaching, such as dealing with students who are difficult or disruptive. A sweet, polite, and clear voice is important because it allows the teacher to communicate effectively with students. Good communication skills are important because they allow the teacher to explain concepts clearly and to answer students’ questions effectively. Superstitions are not necessary for a teacher to be effective because they do not have any bearing on the teacher’s ability to teach.
