The correct answer is A. Only I and II follow.
The statement says that a large number of students studying in municipal schools could not pass the Xth Std. Board examination, causing frustration among the students and their parents. This suggests that there is a problem with the quality of education in municipal schools.
Course of action I suggests that the municipal authority should immediately review the position and initiate measures to improve the situation. This is a good course of action, as it would allow the municipal authority to identify the specific problems with the quality of education in municipal schools and take steps to address them.
Course of action II suggests that the municipal authority should immediately fill up the teachers’ vacancies in the municipal schools. This is also a good course of action, as it would help to improve the quality of education in municipal schools by ensuring that there are enough qualified teachers to teach the students.
Course of action III suggests that the municipal authority should close down some of their schools and concentrate their attention on remaining schools to improve the conditions. This is not a good course of action, as it would deprive students of access to education.
Therefore, only courses of action I and II follow.
