Which of the following can be considered as an example of flow variable?
(i) Production of rice
(ii) Import of cloth
(iii) Change in capital

Correct option is C

The correct answer is (c) All of (i), (ii) and (iii).
Flow variables are measured over a period of time.
(i) Production of rice is a flow variable because it is measured over a specific period, such as a year.
(ii) Import of cloth is a flow variable because it is measured over a specific period.
(iii) Change in capital can also be considered a flow variable because it represents the difference in capital over a specific period.
Therefore, all (i), (ii), and (iii) can be considered examples of flow variables.
