Answer:Id
Explanation:
Id is part our personality system that is more demanding and want to fulfill our desires at any cost. It has no sense of considering other people's needs or how they will feel when we do certain things , it only considers us and no one else. It can't wait, it requires that we fulfil our desires right there and then. This is why a four year old is impatient to wait for his turn to play with toys but he would rather grab them because the id tells him not to wait for his gratification but take it now.
