Maya and a group of friends are organizing a play for one of their classes. The group uses an app to communicate with each other about what materials to get for their costumes. Maya starts seeing ads for some of the materials the group decided to get. Why might Maya be seeing these ads?

1.Maya is seeing the ads that everyone else in school sees.
2.The websites asked the teachers which materials students needed for their project.
3.The messaging app is sharing data with online advertisers.
