Answer:
A. feel safe and more confident.
Step-by-step explanation:
An avatar can be defined as an image, icon or figure that graphically represents an end user or the user's character (personality). It is also referred to as a profile picture or user's identity on an internet forum, video games, etc.
Basically, an avatar isn't a true representation of a user because it typically involves the use of an icon, symbol or digital image rather than an authentic (real) image.
Generally, an avatar is mostly used by people who wishes to conceal their identity or remain anonymous over the internet. Thus, other members of the web wouldn't be able to tell exactly who is operating a particular account with an avatar.
For example, a child that has been a victim of any form of abuse either physically or psychologically may choose to use an avatar so as to conceal his or her identity from the general public, thereby boosting his or her confidence, morale and safety.
Hence, avatars can help abused children feel safe and more confident.
