Answer: F

Exp: First of all you need to understand what a clickstream data is. Clickstream data are groups of clicks in sequence made by a website visitor. For example you searched for Hadoop Learning Training on Google and google re-direct you to one of the free trainings on the Youtube.com which shows videos published by HadoopExam.com and you click the link of the HadoopExam training channel on the YouTube and then it will show you channel page and from there you click HadoopExam.com home page. On the Home Page you will be clicking on the Hadoop Professional Training.

So there are almost 4 links/clicks involved Google Search result, YouTube Channel, HadoopExam home page and then finally training page. Which can help you to reach the final destination. So a data scientist can use these clickstream to find the search/usage patterns and then find the relationship between YouTube videos and the website user interested in so accordingly they can target the customer or user.
