There is a slight error in the title of this question :)
Instead of ‘if my dad would let me’, it’s ‘had my dad let me (remember this useful phrase ending). This is because you can’t have a double ‘would’ in the same phrase.
Explanation:

After getting admission in this school,you must know some things for adjustment. Here, teachers of best qualifications are provided and studies get tougher in higher grade .

So all the things I have told u , u must obey them .Give regards to mother and father.
I’m guessing C since the first excerpt is like a list of the regulations and the second excerpt mentions the “panic” of the regulations and the quarantine measures put in place hope this helps :)
