(a) Inner speech is the correct answer according to Lev Vygotsky's theories on cognitive development. Vygotsky emphasized the importance of inner speech as a crucial component of self-regulation in children. Inner speech, which develops from external conversations through social interactions, becomes internalized and serves as a means for children to think and plan independently. This internal dialogue helps children to organize their thoughts, control their behavior, and solve problems, thereby playing a significant role in self-regulation.
