Because answer B is different.

The rest of the answer looks for stable electonic configuration and either gives/take electron to ensure that it gets the stable electonic configuration. Berylium is in the 2nd group and it should be getting B2+ not B3+. So, it is not in a stable electronic configuration. Therefore it is different.
