Answer:
a. A spiritual belief that young children learn from their parents.
Step-by-step explanation:
The concept of "object constancy" was introduced by Margaret Mahler and refers to a developmental milestone in cognitive development that occurs around age 2, this concept refers to the fact that children realize that people or objects continue to exist in the world even when they are out of sight. (before that, when playing peek-a-boo with toddlers, they have so much fun because they actually think they are disappearing from sight. This also explains why younger kids close their eyes when they don't want to be seen as if this action would make them disappear).
When kids develop "object constancy" they know that even when someone leaves, they will eventually return and therefore this makes people trustworthy, consistent and reliable.
Therefore, the only statement that does not refer to the definition of "object constancy" is a) A spiritual belief that young children learn from their parents.
