Answer:
D
Step-by-step explanation:
A is wrong due to the simple fact most people can't remember everything they did last week let alone something so specific.
B is wrong because how many people know the phone numbers of their friends or parents, let alone the numbers of their parents' friends.
C is a random fact most people probably haven't researched let alone memorized.
E is actually a decent answer, but most people learn and memorize their birthdate first.
