Correct Option: B. When the fund is established and every time it is replenished Detailed Explanation: A petty cash account is a small amount of cash that a business keeps on hand to pay for minor expenses without having to write a check or use a credit card. Understanding when to debit this account is crucial for accurate financial reporting and cash management.

1. Establishing the Petty Cash Fund:
2. When a petty cash fund is first established, the business needs to record this transaction in its accounting system. This is done by debiting the petty cash account and crediting the cash or bank account from which the petty cash is drawn.
3. Example: If a company establishes a petty cash fund of $500, the journal entry would be:
   • Debit: Petty Cash $500
   • Credit: Cash/Bank $500
4. Replenishing the Petty Cash Fund:
5. Over time, as petty cash is used for various small expenses (like office supplies, postage, etc.), the cash balance will decrease. To maintain the petty cash fund at its established level (the "float"), the business will need to replenish it.
6. When replenishing the petty cash, the business will debit the petty cash account again to reflect the increase in cash available. The expenses incurred will be recorded in the appropriate expense accounts (like Office Supplies Expense, Travel Expense, etc.), and the cash account will be credited.
7. Example: If $300 has been spent from the petty cash fund, the replenishment entry would be:
   • Debit: Office Supplies Expense $300
   • Debit: Travel Expense $200
   • Credit: Cash/Bank $500 (to replenish the petty cash back to $500)

Why Other Options Are Incorrect:

• Option A: When the fund is established and every time money is spent:
• This option is incorrect because while the petty cash account is debited when the fund is established, it is not debited every time money is spent. Instead, expenses are recorded in their respective accounts, and the petty cash account is only debited when it is replenished.
• Option C: When the fund is established and when the size of the float is decreased:
• This option is misleading. The petty cash account is not debited when the float is decreased; rather, it is debited when the fund is established and when it is replenished. Decreasing the float typically means that cash is being used up, which does not require a debit to the petty cash account.
• Option D: Every time money is drawn from the petty cash:
• This option is incorrect because the petty cash account is not debited every time money is drawn. Instead, the cash is simply taken from the petty cash fund, and the expenses are recorded separately. The petty cash account is only debited when the fund is established or replenished.

Summary of Key Points:

• The petty cash account is debited when the fund is established and when it is replenished.
• Expenses paid from petty cash are recorded in their respective expense accounts, not in the petty cash account.
• Proper management of petty cash ensures accurate financial reporting and helps maintain control over small expenditures.
• Understanding the correct accounting treatment for petty cash is essential for effective cash management in a business.
