Quizplus · Accepted Answer

Seasonal variations refer to the periodic patterns in time series that repeat themselves within a calendar year or less, such as the regular increase in retail sales during the holiday season. Choice A (Constant variations) suggests a stable pattern of variation, which is not necessarily periodic. Choice B (Cyclical variations) may refer to patterns that occur over longer time periods and are not necessarily yearly. Choice D (Regular variations) is vague and does not provide as specific a description as Seasonal variations.
