The question asks for the exception (what is NOT a limitation). Let's examine each: (A) The choice between different alternative accounting treatments IS a limitation - it creates inconsistency and comparability issues, (B) Trend towards rigidity IS a limitation - it reduces flexibility and may not suit all businesses, (C) Accounting Standards CANNOT override the statute IS a limitation - this means laws take precedence over standards, limiting their authority. Since A, B, and C ARE all limitations of Accounting Standards, the answer is D (all of the above) - meaning all the listed items are limitations, so none of them is an exception.
