Answer:
D.)
Step-by-step explanation:
A person's persona is basically like an O.C. (own character). It is a way of making something or someone that represents you as something that you'd rather be or look like.
So, by making one of these, it is a way to show yourself without completely doing so. So, just as the answer says: it is basically a different identity that is used to interact online without showing your personal features. (Unless your persona looks identical to what you look like, then that doesn't count.)
I hope this helps.
