D. Small expenditures on long- lived assets, such as ` 20 for a paper weight.

C. A revenue expenditure is an expenditure whose benefit expires within the current
accounting period and is in the nature of recurring and is therefore written off to P&L A/c. Sales tax

benefit is going to last for more than one accounting period and hence not a revenue
expenditure
