Answer:
create a web source ( D )
Explanation:
web Animation: in web animation your goal is to pass a message through videos or pictures or even passing a message through an undercover image. this isn't your goal so creating a web Animation isn't going to help out
Web application: you can pass several information like videos and pictures and even text based information but to access it the client has to download and run it on a web browser and this isn't your goal either,so this is a bad idea.
Web source: is more a less a online source for an information, it takes online users to online materials that they can read for information kike newspapers,magazine etc hence this what you need to create to meet your goal.
Web page is what makes up a website they are written in HTML and is translated by the web browser a web page might contain a video or text
