Answer:
B. Jigsaw puzzles.
Step-by-step explanation:
Reflection upon one´s own identity, one´s consciousness through time and in time, is a philosophical topic that has puzzled thinkers for as long as thought has been present in humanity. In order to elaborate this topic through a fictional character, it would be fitting for a writer to use as a symbol the figure of a jigsaw puzzle since it, just like one´s own identity, seems to be comprised of pieces and fragments that one needs to place in a given order and arrangement —through effort and attention— in order to catch a glimpse of the overall image hidden in the composability of the pieces.
