Educational psychology divides the sources of motivation into natural or inborn causes and acquired causes. Natural causes are present in a learner from birth and work without any training, and the usual list of them includes instincts, feelings, the urge for self preservation, bodily needs and the hidden layer of the mind.

Among the alternatives offered, the stirring of feeling that rises on its own in every child and pushes behaviour towards a goal belongs to this inborn group, because such arousal needs no earlier learning and no social training before it can appear.

A liking for a particular object and a settled way of acting are both built by repeated contact with things, persons and activities, so they are counted among the acquired sources. The refinement of disposition that upbringing and surroundings slowly build into a child is in the same way a product of experience rather than something carried from birth.

Impulse option is correct.
