Statement I is accurate; the business environment's components (political, economic, social, technological) differ across nations, rendering it dynamic.
Statement II is also accurate. Rapid and unpredictable external changes (e.g., pandemics, wars, technological disruptions) impede businesses' ability to forecast future conditions.
Therefore, both statements accurately identify two distinct business environment characteristics: dynamism and uncertainty.
Final Answer: (C) Both the statements are true.
