During which substage of piaget’s sensorimotor stage does the child "begin to act upon the outside world," in which infants seek to repeat enjoyable events in their environments if they happen to produce them through chance activities?
a) substage 2: first habits and primary circular reactions
b) substage 1: simple reflexes
c) substage 3: secondary circular reactions
d) substage 4: coordination of secondary circular reactions

A) Substage 2: First habits and primary circular reactions

Explanation:

At this stage, the baby collects and analyzes the information through their senses and their ability to interact with the environment. Babies increase their knowledge of the world through the experiences they live with the manipulation of objects. The principle that best describes the concept of the infant's object is "out of sight, out of existence." The object exists in the child's mind only, as long as the child is in direct sensory or motor contact with him.
