The concept of secure attachment in infants is rooted in attachment theory, which posits that the quality of the relationship between a caregiver and an infant can significantly influence the child's emotional and social development. Research has consistently shown that a substantial majority of infants develop secure attachment styles.

Typically, studies indicate that around 60% to 75% of infants form secure attachments to their primary caregivers. These infants feel safe and are more likely to explore their environment while using their caregiver as a secure base. This level of secure attachment is crucial for healthy emotional regulation and forming future relationships.

The other percentages presented are considered atypical for secure attachment rates. Lower percentages like those in the other options suggest a smaller proportion of infants achieving this critical attachment, which does not reflect the widely accepted findings in developmental psychology. Thus, the correct choice reflects a well-supported understanding of attachment patterns among infants.
