The correct answer is: C. Security premium reserve
An undistributed profit is a profit that a company has earned but has not yet paid out to shareholders in the form of dividends. It is typically held in a reserve account, which is a type of account that is used to accumulate funds for future purposes.
General reserve accounts are used to accumulate funds for general corporate purposes, such as to meet unexpected expenses or to make capital investments. Employee compensation reserve accounts are used to accumulate funds to pay for employee benefits, such as pensions or severance pay. Dividend equalization reserve accounts are used to smooth out the amount of dividends that a company pays out each year.
Security premium reserve accounts are used to accumulate funds from the sale of shares at a premium above their par value. The premium is typically used to offset any losses that the company may incur in the future.
Therefore, the only option that is not an undistributed profit is security premium reserve.
