Answer:
D). I always round the numbers when making a budget, so everyone must round numbers to make a budget.
Step-by-step explanation:
Facts are characterized as the 'fundamental reality or truth that has the ability to be verified or proved.' While an assumption is 'the supposition of something on the basis of one's own belief without any proof.'
As per these definitions, the last statement among the given options exemplifies an assumption and not fact. The belief that if one round off the numbers while preparing a budget makes it necessary for everyone to do it is not only based on one's individual belief system but can not be proved as well. Thus, option D is the correct answer as the deductions or the reasoning in the above statements can be justified and proved.
