Answer:
B. texting and email communication
Explanation:
Compare and contrast essays should have topics that are somehow in the same category. In this case, the answer choices are looking for 2 topics that have the same purpose. Both texting and emailing are used to respond to a person. They are forms of communication that allow a person to communicate their ideas. However, they are still not the same thing entirely so they can be contrasted.
Postcards and conversations are not meant for the same reasons. They cannot be compared because they are not made for the same thing. Postcards are not made to convey long ideas for share in-depth information like conversations. Additionally, texting and answering machines are different because answering machines take information when texting is not available. So they cannot be compared because they were not made to replace each other or be used instead of the other.
