A. Enable the Combine CSS optimization: This approach combines multiple CSS files into one to reduce requests, which is beneficial for static content optimization but not directly useful for dynamic content like stock prices.
B. Create a static content group: Static content groups are used for content that does not change often, which does not apply to stock prices that frequently update.
C. Create a dynamic content group: Dynamic content groups are designed for content that is frequently updated. This would allow the engineer to cache the stock price data temporarily, serving it quickly to multiple users without repeatedly querying the backend systems, thus improving the performance for this particular content.
D. Enable the Minify JavaScript optimization: Minifying JavaScript optimizes the size of JavaScript files but does not affect the server-side performance related to dynamic content fetching like stock prices.
