In accounting, the terms debit (Dr.) and credit (Cr.) refer to the two sides of an account in the double-entry accounting system.

Definition of Debit and Credit in Accounting:

Every financial transaction affects at least two accounts in a double-entry system: one account is debited, and another is credited.

Debits (Dr.) appear on the left side, while credits (Cr.) appear on the right side of an account.

Accounting Equation:

Step-by-Step Justification:Assets=Liabilities+Equity\text{Assets} = \text{Liabilities} + \text{Equity}Assets=Liabilities+Equity

Debits increase assets and expenses.

Credits increase liabilities, equity, and revenues.

Why the Other Options Are Incorrect:

A. Debit indicates the right side of an account and credit the left side ❌

Incorrect, as debits are always recorded on the left side, and credits are always on the right side.

B. Debit means an increase in an account and credit means a decrease. ❌

Partially incorrect; it depends on the type of account:

For assets and expenses, debits increase and credits decrease.

For liabilities, equity, and revenues, credits increase and debits decrease.

D. Credit means an increase in an account and debit means a decrease. ❌

Also incorrect because increases and decreases depend on the type of account (e.g., debits increase assets but decrease liabilities).
