D Correct answer
Explanation

Nielsen collects TV ratings data through People Meters (electronic devices), Set Meters (attached to TVs), and Diaries (manual household logs). They don't use letters from households as a formal data collection method - this would be unreliable and non-standardized. Household letters are not a systematic ratings measurement methodology.
