Explanation

Option D is correct because when a Cookie is created without calling setMaxAge() (or with setMaxAge(-1)), it becomes a session cookie - stored only in browser memory and destroyed when the browser window closes. This is the default cookie behavior in the Java Servlet API.

A is wrong - Server shutdown has no bearing on client-side cookies; cookies live in the browser, not the server process.
B is wrong - Garbage collection of servlet instances is a server-side JVM event and has no connection to browser-stored cookies.
C is wrong - A cookie does survive the current request; that would describe a request attribute (request.setAttribute()), not a cookie.

Memory tip: Think of it as three scopes: request dies with the request, a session cookie dies with the browser, and a persistent cookie (set via setMaxAge(seconds) with a positive value) survives browser restarts. No setMaxAge call = session cookie = browser shutdown.
