The nurse is caring for a hospitalized 3-year-old child. Their parents tell the nurse that they will be back to visit at 6 PM. When the child asks the nurse when his parents are coming, the nurse's best response is:

A. A 3-year-old has a limited understanding of time, so referencing an event like "after dinner" is more appropriate and meaningful to the child. B. While comforting, this option does not provide a concrete understanding for a child of this age. C. Saying "soon" can be vague and cause more anxiety, as the child may not understand what "soon" means. D. A 3-year-old is unlikely to understand the concept of time or how to read a clock, so this explanation may confuse the child.
