A smartphone can run the interactive video for the child and also be used for the parent's urgent call (e.g., via features like call - video multitasking or using another device? Wait, no—wait, the parent is using a smartphone for the call, and the child needs a mobile tech for interactive video. Wait, no, the options: tablet is mobile, but wait, the parent is using a smartphone for the call, and the child's device? Wait, no, the question is "which mobile technology allows this action (parent makes call on smartphone, child is entertained with interactive video)". Wait, maybe the parent uses the smartphone to both call and play the video? But no, the parent is on a smartphone call, so the child needs another mobile tech? Wait, no, the options: tablet is a mobile device that can play interactive videos, while laptop (not mobile), e - reader (mostly for reading), smartphone (parent is using it for call).
