The accounting equation embodies the duality principle

Steps:

• Recall the basic accounting equation: Assets = Liabilities + Owner's Equity.
• Identify that this equation shows every transaction affects two accounts, maintaining balance.
• Link this balance to the duality concept, which states debits equal credits in double-entry bookkeeping.
• Eliminate other options by matching them to unrelated accounting principles.

Why B is correct:

• Duality, or double-entry bookkeeping, is directly represented by the equation, ensuring every financial transaction has equal debits and credits to keep assets balanced with liabilities and equity.

Why the others are wrong:

• A: Business entity separates company finances from owners, not shown in the equation.
• C: Going concern assumes the business continues indefinitely, unrelated to the equation's structure.
• D: Realisation records revenue only when earned, not tied to the assets-liabilities balance.

Final answer: B
