Which of the following pertains to Cash Flows from Investing Activities?

Cash flows from investing activities primarily involve transactions related to the acquisition and disposal of long-term assets, such as property, plant, and equipment. In this context, changes in production equipment directly reflect cash spent on purchasing new equipment or cash received from selling old equipment. These transactions are crucial for assessing how much a company is investing in its future operational capacities, impacting long-term viability and financial health.

The other choices do not pertain to investing activities. Changes in current liabilities relate to short-term obligations and affect operating activities. Cash dividends declared represent returns to shareholders, which are financing activities. Revenue from sales is part of operating activities, reflecting the core business transactions that generate income. Understanding the distinction between these categories helps in analyzing a company's cash flow and financial performance comprehensively.
