Answer:
The correct answer is C. Xander has not yet attained object permanence. 
Explanation:
According to Piaget's Stages of Cognitive Development, object permanence occurs during the <em>Sensorimotor Stage (birth- 2 years old)</em>, in which an infant understands that an <em>object is still there even if it cannot be seen. </em>
In this case, Xander has not yet obtained object permanence since as soon as the rattle is taken away, for him it has <em>ceased to exist</em>, thus making him be interested in other stimulus.

The correct answer to this open question is the following. 
The process of learning involves perception, the way we perceive things from the environment or in school. Then it comes to process the information, which means the wat we think about what we are observing. We reflect on it and conceptualize to better understand. Then, we have to put into action what we learn in order to totally understand it. To master what we learn, we have to practice it once or twice until we get it.
