When trying to determine the most appropriate response for questions like this, what you will need to do is figure out the relationship between the first set of words.  In looking at the words “transition” and “change,” it can be determined that the two words are similar in meaning; thus, they are synonyms.  As such, when looking at “immobility,” you’ll need to provide a synonym.  When thinking about this, what other words come to mind that mean basically the same thing?  What may have come to mind are the words “stasis,” “stillness,” “nonadjustable,” etc.  Any of these words (or similar words) will work well to complete this relationship question.
