Using standard alphabetical filing rules, which name is filed first: Lorna Ramos, Lito Ramirez, Luz Ramil, Leo Ramones?

The correct answer is C. Luz Ramil

Indexed surname first, the filing order is RAMIL, Luz → RAMIREZ, Lito → RAMONES, Leo → RAMOS, Lorna. The name filed first is Luz Ramil. The surnames all begin with "Ram", so the fourth letter decides: i (Ramil, Ramirez) comes before o (Ramones, Ramos), and "Ramil" is shorter than "Ramirez".
