Answer:
4 years old
Step-by-step explanation:
Empathy begins to emerge at this age and there is less selfishness. Children at this age are beginning to understand how others feel and that they actually have feelings too. They can tell when a person is sad or hurt. This is seen in the example question where the child does not show her rejection of the toy outrightly to her uncle by crying or showing temper tantrums but rather shows acceptance so as not to hurt her uncle's feelings.
