Answer:
Desert Company
The date on which Desert Company can begin capitalizing interest costs is March 1, 2021.
Step-by-step explanation:
This is the date it obtained the construction loan for 3 years. Desert should only capitalize interest during the construction period. This is the period when the asset is being prepared for its future use. Interest can only be capitalized when the related asset will yield future economic benefits. Otherwise, it should be expensed.
