Correct answer: A. Method for common data entry
Explanation: The direct answer is A: a method for common data entry. When different employees use different formats, the same information may appear in different orders, spellings, or units. The organisation should define one method: specify the fields, order, date format, units, required entries, and checking steps. Then employees follow the same pattern, making records easier to compare, search, and understand. Option A is correct because a common data-entry method directly standardises the work causing the confusion. Option B, changing the owner, does not create a common format. Option C, a festival programme, is unrelated to recording data. Option D, changing the company name, changes identity but not data practices. A method is the most direct planning choice because it guides how the task is performed. Memory cue: when people perform the same task differently, standardise the method before changing anything unrelated.
