Option 1 -> Purchase of war tanks creates capital assets (defense equipment) with long-term utility.
Option 2 -> Capital receipts are inflows like loans or sale of assets, not expenditures.
Option 3 -> Revenue expenditure is for routine operations and doesn't create assets.
Option 4 -> Revenue receipts are inflows like taxes, not expenditures.
Hence, Capital expenditure -> The purchase of war tanks by the Indian government from Russia is classified as capital expenditure because it results in the acquisition of a capital asset (defense equipment) that will provide services over multiple years. Capital expenditure creates assets or reduces liabilities, unlike revenue expenditure which is for day-to-day operations. War tanks are durable assets that enhance the defense capability of the nation for a long period. -> correct
