Answer:
c. Avoidantly attached
Explanation:
According to Ainsworth, Rachel's lack of reaction is an indicator that Rachel is avoidantly attached to her mother. When children are avoidantly attached they do not seek comfort in their parents, because parents have shown that they are emotionally unavoidable for them. How the first caregivers interact with an infant during the first few months of its life determines the type of attachment. If the parent is unavoidable this will create an insecure attachment.
