Hi !!
A- Knowing when to use the pronoun tu or vous and related familiar or formal expressions is very important. Tell the following people to do or not to do the things mentioned, using imperatives and the appropriate forms (assuming you are a teenager).
1- Nettoyez la cuisine cet après-midi ! (your cleaning mady ==> formal vous) (Clean the kitchen this afternoon) (Nettoyer = nettoie, nettoyons, nettoyez)
2- Ne fais rien à Pâques ! (Faire = fais, faisons, faites) (your mom => tu)
3- Allez à la campagne pendant les vacances d'été ! (aller = va, allons, allez) ("vous" plural = your neighbors or "tu" formal 'your neighboor')
4- Regarde ce film la semaine prochaine ! (words for words, it's "vois ce film... but in french we would say "va voir ce film..." . So I replace "see" by "watch" because in french it sounds better. Voir = vois, voyons, voyez/ regarder = regarde, regardons, regardez
B & C are okay !
