The primary function of the Balance Sheet is to:?

The correct answer is (D)

because a balance sheet shows your business’s assets, liabilities and shareholder equity at a specific moment.

Creditors and interested stock investors use the balance sheet to determine a company's financial standing (value) because it lists what a company owns and what it owes. Thus, the balance sheet shows the company's value as of a given point in time.

Errr ... none of these. 

It is simply a statement of the company's assets and liabilities, at the close of business on the stated day, according to the chosen accounting standards.

The "balance" part is basically a type of "checksum" that is part of commonly accepted accounting standards - it really just makes it easier to spot a mistake.

The company's "value" is given by its stock market valuation, not by the balance sheet.
