The correct answer is: C. Value of plant and machinery
The money measurement concept is one of the accounting concepts that states that only transactions that can be expressed in monetary terms should be recorded in the books of account. This means that the health of the managing director of the company, the quality of the company’s goods, and other non-monetary items are not recorded in the books of account.
The value of plant and machinery is a monetary item and is therefore recorded in the books of account. Plant and machinery are assets that are used in the production of goods or services. They are recorded at their historical cost, which is the amount of money that was paid for them when they were purchased.
The other options are not recorded in the books of account because they are not monetary items. The health of the managing director of the company is a non-monetary item that cannot be expressed in monetary terms. The quality of the company’s goods is also a non-monetary item that cannot be expressed in monetary terms.
