I'm not sure why the question mentions 'momentary time-sampling data' - it seems like they're just looking for frequency of hand-slapping. Option C seems like overkill. I'd go with Option A.

Option C is the best method for recording momentary time-sampling data. Dividing the observation period into 2-minute intervals and recording whether hand-slapping occurs at any moment during each interval provides the most detailed and accurate data.
