  1. Only when it flies at night
  2. Before every cross-country flight
  3. Carrying a person for hire ✔

Why: An aircraft carrying a person other than crew for hire, or provided by an instructor giving paid instruction, must have had an annual or 100-hour inspection within the preceding 100 hours of time in service.

Huh, didn't know that: An annual inspection can count as the 100-hour inspection, but a 100-hour does not replace the annual.
