Q1
B — A safe username never shows your address. Line 2 should use a nickname like "BlueFox" instead of the address.
Q2
A — Line 1 uses a full name. A safe username uses a made-up nickname such as "SkyTiger" instead.
Q3
A — The username has a birth year (2013) in it, which gives away personal information. It should leave the year out: "CoolCat".
Q4
C — A safe username must not include your school. Line 3 should set username to the nickname.
Q5
B — The check is the wrong way round. A safe username must NOT contain the school name, so it should say not in.
