During which substage of Piaget's sensorimotor stage does the child begin to act upon the outside world, a process by which infants seek to repeat enjoyable events in their environments if they happen to produce them through chance activities?

c) Substage 3: Secondary circular reactions

Explanation:

Piaget's theory posits that children go through four different stages of cognitive development. Their mental development includes language, morals, memory and the like.

The sensorimotor stage is the earliest in Piaget's theory of cognitive development and is described as a period of tremendous growth and change.

It is divided into substages, the third of which is called SECONDARY CIRCULAR REACTIONS where the child becomes more focused on the outside world and begins to repeat activities to derive joy from them such as picking up a toy to put in their mouth.
