Step 1: Understanding the Concept:
This question tests knowledge of attachment theory (Bowlby) and separation anxiety in child development.
Step 2: Detailed Explanation:
Assertion A:
Separation anxiety does emerge when a child has formed a clear-cut attachment with the mother (or primary caregiver).
This typically occurs around 8-12 months of age.
This statement is true.
Reason R:
When there is clear-cut attachment, the child uses the mother as a secure base to explore the environment.
This is called the "secure base phenomenon" in attachment theory.
This statement is true.
Relationship between A and R:
Both statements are true but they describe different aspects of attachment.
Separation anxiety is the distress when the caregiver leaves, while exploring the environment is the opposite behavior.
R does not explain A - they are complementary but not causally linked.
Step 3: Final Answer:
Thus, both A and R are true but R is NOT the correct explanation of A, which corresponds to option (B).
