D Correct answer
Explanation

A JSP declaration variable x is static/instance-scoped and persists across requests. Initially, jspInit() is called once during translation/loading (printing/incrementing x to 1). On the first request, &lt;%= x++ %&gt; prints 1 (now x is 2), then prints 3 in the scriptlet. On the second request, &lt;%= x++ %&gt; evaluates to 3 and prints 3.
