An organisation's expense can be categorised into three groups:
Fixed Costs - costs that do not change with output.
Variable Costs - costs that vary in direct proportion to output.
Semi-variable costs - costs that are a combination of the above, with both a fixed and variable element.
Among the four options:
"Land rental paid in advance": This is fixed cost. The rental won't increase when the production increases.
"Additional pallet hires due to higher demand in year-end season": This can be identified as semi-variable cost (or step cost).
"Governments taxes": The taxes are often levied by a percentage of income or revenue. Therefore, it is variable
"Raw materials for next year production": This is obviously variable cost.
