Emotional expression, such as crying and smiling, serves as an early form of communication between parents and young infants. Infants use these expressions to convey their needs and emotions, and parents use them to respond appropriately to their infants' needs.

Answer: D
 Emotional expression helps to reduce negative affectivity and increase positive affectivity in infants. Crying may indicate discomfort or distress, and smiling may indicate pleasure or contentment. When parents respond to their infants' emotional expressions in a nurturing and supportive way, it can help regulate the infants' emotions and promote their emotional development.
