Answer A is not correct because the rule that it states, while true as far as it goes, does not control the situation presented. It is true that the federal rule provides that a voluntary dismissal ol a claim by a plaintiff is \"without prejudice.\" See :RCF' 41(a]{1). But this rule applies only if the notice of dismissal is led \"before the opposing party serves either an answer or a motion for summary judgment" or with \"a stipulation of dismissal signed by all parties who have appeared.\" FRCP 41(a) (1){A)(i} and (ii). Here, the problem states that the defendants had already answered the complaint, and a signed stipulation was not filed. Moreover. even if Plaintiff had led the notice of dismissal before the defendants' answer. the dismissal could be without prejudice only it Plaintiff had not previoust dismissed any federal or state action based on the same claim. See FRCP {a}(1)(B)
