In the hierarchy of generally accepted accounting principles, APB Opinions have the same authority as AICPA:

Choice "d" is correct. AICPA Accounting Research Bulletins, FASB Standards, FASB Interpretations,

FASB Staff Positions, FASB Statement 133 Implementation Issues, and APB Opinions and

Interpretations are the most authoritative sources of generally accepted accounting principles.

Choice "a" is incorrect. AICPA Statements of Position, AICPA Accounting and Auditing Guides, and

FASB Technical Bulletins are secondary sources of generally accepted accounting principles.

Choice "b" is incorrect. AICPA Statements of Position, AICPA Accounting and Auditing Guides, and

FASB Technical Bulletins are secondary sources of generally accepted accounting principles.

Choice "c" is incorrect. AICPA Issues Papers and Practice Bulletins, FASB Concepts Statements, and

other authoritative pronouncements are tertiary sources for generally accepted accounting

principles.
