Answer: d. Net income is part of the computation for ending retained earnings.
Explanation:
In the statement of owner's equity, Retained earnings are calculated and it is done with the Net Income. This is why when the net income is calculated from the Income Statement it is transfered to the SOE and used to calculate Retained Earnings.
Retained Earnings are calculated by the formula,
Ending Retained = Opening Retained Earnings + Net Income (losses) - Dividends
Net income is added to (or subtracted from if it is a Net loss) the Opening Retained earnings balance. Net dividends are also subtracted.
