The concept of attachment in developmental psychology specifically refers to the emotional bond that develops between an infant and their primary caregiver. This bond is critical during the early stages of development, as it influences the infant's emotional and social growth. Research has shown that secure attachment leads to healthier relationships later in life, enhancing the individual’s ability to form stable connections with others. Factors such as responsiveness and sensitivity of the caregiver contribute significantly to the quality of the attachment.

In contrast to the other options, which involve bonds formed under different circumstances or with different types of relationships, the attachment bond described in option B is foundational in the context of a child's development. While friendships and peer relationships are important, they develop later and are built upon the earlier frameworks established through attachment to caregivers.
