Your application's main dashboard has multiple child components displaying real-time data. To optimize performance, which strategy would you employ to ensure only relevant components are re-rendered upon data changes?

In this scenario, to ensure only relevant components are re-rendered upon data changes, you should use Pure Components. Pure Components are optimized to re-render only when their input properties change, and they don't have side effects. Memoization (Option 1) can be used for caching expensive calculations but doesn't handle re-rendering. Dynamic Imports (Option 3) and Lazy Loading (Option 4) are related to code splitting and module loading, not component rendering optimization.
