Which of the following statements is TRUE concerning packet delay variation as it relates to the delivery of streaming media (like audio or video):Question 13AnswerPacket delay variation is not important for audio or video delivery because it only occurs in packet-switched networks, and these are not used for streamed mediaIf packet delay variation occurs, it means that the network is congested and therefore streaming media could not be supportedLarge packet delay variation never impacts on the quality of streamed media because a buffer can be used to smooth it outPacket delay variation is a bigger problem for communicative services (like a videophone call) than for retrieval services (like Netflix)

Solution
The correct statement is: "Packet delay variation is a bigger problem for communicative services (like a videophone call) than for retrieval services (like Netflix)".
Packet delay variation, also known as jitter, can cause problems in real-time communication services like videophone calls because it can lead to uneven quality and disruptions. This is because these services require a steady stream of data packets to maintain the conversation in real time.
On the other hand, retrieval services like Netflix can handle packet delay variation better because they use buffering. This means they load a certain amount of data ahead of what's currently being watched, so if there's a delay in packet delivery, the buffered content can keep playing, providing a smoother viewing experience.
