Explanation:
An online recommendation engine is a set of algorithms that uses past
user data and similar content data to make recommendations for a specific user profile. It also uses competitive filtering to determine what content multiple similar users might like.
They are typically composed of a hybrid of content and collaborative filtering procedures. They are used in a variety of software applications, including music playlist generation, movie choice, targeted advertisements, and restaurant recommendations.
So the option C is FALSE as both the options A as well as B are true
