The correct option is C Profit
Profit or loss earned by the business under single entry system is based
on the difference between its opening and closing capital.
Hence, if
the sum of capital on the last day of the financial year is more then opening capital on the first day of financial year then it is
considered as a Profit.
eg. if the opening capital is Rs . 1,00,000 and
closing capital is Rs. 1,30,000 than Closing capital - Opening capital
will give a Positive Rs.30,000 resulting a Profit.
