Seasonal Variation refers to patterns that repeat within a year with higher demand in some periods.

• A. Pattern repeating within a year with higher demand in some periods
• B. Random fluctuations with no pattern
• C. A long-term trend
• D. Cyclical patterns over several years

Answer: (A)

Seasonal variation is the regular, within-year pattern in demand that repeats as the year cycles, driven by seasons, holidays, weather, and similar factors. This means demand rises in certain periods and falls in others in a consistent yearly rhythm. The option that says a pattern repeating within a year with higher demand in some periods matches this idea exactly, capturing the timing and season-driven peaks.

Why the others don’t fit: random fluctuations have no predictable pattern, so they don’t show a repeatable yearly cycle. a long-term trend describes a gradual increase or decrease over many years, not the regular within-year repetition. cyclical patterns over several years occur over longer, less regular horizons and aren’t confined to a single year.
