Answer 2

Answer:

A teacher should be friendly with students. Grammatically, a is wrong, c is wrong and D is also wrong. There is a probability that a teacher should be friendly so that it is used as an preterite form of a modal verb and the present form is shall. Should is actually used as a past tense of shall. The present will be a teacher shall be friendly with the students.
