Premise: Company X discovered that employees that have lunch before 13:00 are more productive than employees who have lunch after 13:00 or skip lunch altogether.

Conclusion The company management concludes that it needs to encourage her employees to have their lunch no later than 13:00 so as to increase employee productivity.

Option A - Incorrect
This claim is not true about the passage because the fact that employees are having their lunch at the same time does not mean there will be an increase in productivity. An increase in employee productivity is subjected to those that have lunch before 13:00. So, if all employees, for instance, have lunch after 13:00 or skip lunch, there will be a decrease in productivity as compared to them having lunch by on or before 13:00.

Option B - Incorrect
This claim is out of context as there are no statistics on the age range of employees that have lunch before 13:00.

Option C - Incorrect
Jane? This has no correlation to the passage in consideration.

Option D - Correct
This claim proves a reasonable point with respect to Company X's discovery on employees' productivity. Their competitor, Company Y, with highest employee productivity could have been the reason Company X is looking for a way forward to increase her employees' productivity.

Option E - Incorrect
This claim is baseless and out of context with respect to this passage.
