Which of the following options does a defendant NOT have when notified of a lawsuit?

A defendant, upon being notified of a lawsuit through a summons, has various legal avenues available to them to respond to the allegations. Options like filing a counterclaim, filing a motion to dismiss, or filing an answer are formal methods through which a defendant can articulate their position or contest the claims made against them.

Choosing to ignore the summons, however, is not a legitimate option for a defendant. Doing so leads to significant consequences, such as a default judgment being entered against them. This means the plaintiff could win the case without any input or defense from the defendant simply because they did not respond to the legal notice. Therefore, while a defendant has the choice to engage with the legal process actively through the available options, ignoring the summons is not a viable or advisable strategy and ultimately undermines their rights in the legal proceedings.
