Which of the following qualifies as an excited utterance?

An excited utterance is defined as a statement made by a declarant while under the stress or excitement of a startling event or condition, which is considered an exception to the rule against hearsay. The key aspect of an excited utterance is that it occurs spontaneously in response to a startling event, reflecting the declarant's emotional state without the opportunity for reflection or fabrication.

In the correct choice, a spontaneous statement made in response to a startling event exemplifies the essence of an excited utterance. This situation typically involves a high level of emotional response from the individual, which can diminish their ability to fabricate or alter the truth of what they are saying. As such, it is regarded as a reliable form of evidence.

The other choices do not meet the criteria for an excited utterance. Statements made during a heated argument might involve strong emotions, but they typically do not arise spontaneously from a startling event, making them less reliable. Deliberate testimony during a court appearance involves a considered and structured account of events, which lacks the spontaneity needed for an excited utterance. Similarly, a written account of past events is reflective and does not occur in the moment of excitement or stress, thus failing to meet the parameters of an excited utterance.
