Answer:
d. All of the above.
Step-by-step explanation:
A question of policy is when one asks a question seeking action and not a mere judgmental response. In other words, a question of policy is when someone questions the policies based on whether something should be done or not.
Considering the given statements/questions, all of them are questions of policy. Asking the question "should" provides a question looking for action and not a judgmental response from the authority. The questions posed are of great importance, directed to the respective authorities, be it the school or college or the government.
Thus, the correct answer is option d.
