Answer:
B, a movie with a character who uses an iPad.
Step-by-step explanation:
Product placement is an indirect type of advertisement in which a product isn't directly advertised. It is increasingly becoming a form of advertisement these days because of the ease with which it is done.
Product placement can also be said to be embedded marketing. That is, the showing or referencing of a product in an unconnected way to another work or thing, e.g. tv, film, etc.
As in the qustion, a movie character using an iPad is doing embedded marketing for the iPad thus attracting the audience to purchase the product.
Cheers.
