How should an Architect address this issue?

A website built on AEM Sites displays the company’s stock price in the footer of all pages. The stock data is retrieved from a third party REST service using two-way SSL and rendered in an AEM component using HTL During performance testing in the last development sprint it becomes apparent that the third party service sometimes takes up to 30 seconds to respond, which degrades the overall site performance.

How should an Architect address this issue?
A . Call the REST service directly from the browser
B . Temporarily remove the component from all content
C . Load the stock data component asynchronously
D . Add a 5 second timeout to the REST call

Answer: C
