Answer:
d) EPS cannot be calculated if a company has no preferred stock. 
Explanation:
The above statement is untrue about E.P.S because the reason why 'Preferred dividend' (which is dividend on preference shares)  is subtracted from Net Income, before being divided by the 'Average Number of Common Shares Outstanding' is for comparability. 
Since the denominator is based on 'common shares' or 'ordinary shares', it makes sense not to include the part of income that has fallen to preferred shares.
As a matter of fact there are a lot of companies that do not have preferred stock and still report Earnings Per Share on their financial statements.
Finally, still on comparability; E.P.S helps to compare the performance of big companies that have preferred stock with small companies that do not have. Hence EPS can be calculated even when there is no preferred stock.
