A. Payment of Dividend: This is a cash outflow, but it falls under Financing Activities in the cash flow statement, not Operating Activities.

B. Payment of employee benefit expenses: This is a cash outflow directly related to the day-to-day operations of a business, so it is part of Operating Activities.

C. Payment of taxes: Paying taxes is also a cash outflow related to the core operations of a business and is classified as part of Operating Activities in the cash flow statement.

D. Purchase of Inventory from suppliers: This is a cash outflow related to acquiring goods for sale, which is part of a company's core operations and falls under Operating Activities.

E. Purchase of furniture for cash: This is a capital expenditure, not directly related to the day-to-day operations, so it typically falls under Investing Activities rather than Operating Activities.

So, the correct answer is 4. B, C, and D only, as these are the cash outflows directly associated with Operating Activities.
