Answer:
D. $2,050,000.
Explanation:
In 2020
Expenditure = 4,000,000
In 2021
Expenditure = 2,050,000 (Change in Design cost is already included)
All the costs incurred to make an asset usable could be capitalized. the change in original construction design is an essential cost and it is incurred before completion / use of city hall. So the cost of 2,050,000 will be added to capital account in 2021.
So the correct option is D. $2,050,000.
