The correct answer is: B. Haptik
Haptik is a messaging app that allows users to send text messages, photos, and videos to each other. It is not a social networking app because it does not allow users to create profiles or connect with other users based on shared interests.
Twitter is a social networking service that allows users to post and interact with messages known as “tweets”. Tweets are limited to 280 characters and can include text, photos, videos, and links. Twitter users can follow other users to see their tweets in their timeline.
Facebook is a social networking service that allows users to create profiles, connect with friends and family, and share photos, videos, and updates. Facebook users can also join groups and pages related to their interests.
LinkedIn is a social networking service for professionals. LinkedIn users can create profiles to showcase their skills and experience, connect with other professionals, and find jobs.
I hope this helps!
