Answer: B - Object permanence is the developed realization in young children that objects exists even if they are not heard, seen or touched.
Key Takeaway: Object permanence is a developmental milestone whereby an infant realizes that an object still exists even though he or she cannot touch, hear or see it. Infants develop this realization around the age of 4 months. This means that they will cry for an object even when it is taken away and hidden because they know it still exists. Before developing this realization, once an object is hidden, they seem to forget about it.
