b. Electricity usage over a 24 hour period
c. Stock prices over a year
d. Number of people having access to a telephone land line over a year

Answer 1

Answer:

b. Electricity usage over a 24 hour period

Explanation:

Seasonality pattern of demand refers to the want or desire for a good which fluctuates as per the seasonal requirements. For example the demand for air conditioners is most during summers and almost nil during winters.

In the given case, Electricity represents seasonal demand in the sense that during day time, when several tasks are to be performed which are dependent on electricity, the usage is most and such usage falls as one moves towards the evening.

Thus, electricity usage over a 24 hour period represents seasonality pattern of demand.
