Answer:
A. filling in missing parts.
Step-by-step explanation:
The question above is related to the subject, "Psychology." This is related to the "Law of Closure" of the Gestalt Law. This is an illusion that we create by filling in the missing parts whenever we see objects that are broken. So even if a circle has a missing part (incomplete stimulus), we tend to see it (unconsciously) as a whole or as a completely closed circle despite having gaps in between.
