Explanation:

Capital budgeting is an accounting method that corporations use to decide which planned acquisitions of fixed assets will be approved and which should be refused.

Some examples of Capital Expenditures include:

  1. Construction of an additional building
  2. Procurement of delivery vehicles
  3. Procurement of new equipment
  4. Rehabilitation of existing equipment

If one of the criteria for classification under Capital Expenditure is that it must be in the plan, then none of the above items mentioned in the question will fly.

Monies have already been expended on the options A, B, and C.

Option D is an offer to purchase an existing asset, not a planned investment. Therefore it also does not qualify.

Hence the correct answer is E.

Cheers!
