Learning involves improvement of skills over time for example improvement of handwriting. Scientist believes there are several phases in the learning process.
The initial improvement phase in learning is the acquisition phase. In the starting of this phase, the learner can not respond correctly without assistance. So in this phase learner learns to connect a neutral stimulus and an unconditioned stimulus with the help of assistance.
At the end of this phase, the organism learned to respond independently to the stimulus. So the correct answer is A.
