Answer:
b. $137,000.
Explanation:
The accounting equation is one that shows the relationship between all the elements of a balance sheet namely; assets, liabilities and owner's equity.
For an entity that purchased a parcel of land (asset) for $85,000 and sold for $137,000, the company that sold the land for $137,000 will derecognize the land and the associated cost while the company that purchased it at $137,000 will recognize it at cost.
The accounting standard IAS 16 requires that the initial recognition of assets should be at cost.
Hence the right answer is b. $137,000.
