Step 1: Recall the definition of current liabilities:
Current liabilities are obligations expected to be settled within one year (or one operating cycle) of the balance sheet date.
Step 2: Check each listed item against this definition:
Sundry creditors (amounts owed to suppliers), outstanding expenses (expenses incurred but not yet paid), and bills payable (short-term promissory obligations) are all settled in the short term, so each independently qualifies.
Final Answer:
All three — sundry creditors, outstanding expenses, and bills payable — are current liabilities.
