Which of the following statements is false regarding intents?

The statement asserting that an implicit intent always results in the system asking the user which app to open is inaccurate. Implicit intents are used to request an action from another app without specifying the exact component to handle the request. When an implicit intent is initiated, if there is only one app on the device that can handle the intent, the system will open that app directly without prompting the user. The choice of whether to prompt the user or not depends on how many apps are available that can respond to the intent.

In contrast, if multiple apps can fulfill the intent, that's when the system presents the user with a chooser dialog. Therefore, while it's true that an implicit intent can lead to a prompt, it does not always do so, making the statement false.

The other statements accurately describe the behavior of intents. For instance, both implicit and explicit intents are indeed used to launch activities, explicit intents do require the specific class of the target activity, and the startActivity() method is the standard way to initiate an activity using an intent.
