Final answer:
The best predictor of adolescents' self-esteem is physical self-esteem, but other factors play a significant role in shaping their overall self-concept.
Step-by-step explanation:
Although research presented in the textbook indicates that physical self-esteem is the best predictor of adolescents' self-esteem, the correct answer to the question is b. Other factors play a significant role. This means that besides the physical dimension of self-esteem, elements such as socio-economic status, peer relationships, family environment, education, and various psychological factors also contribute significantly to an adolescent's overall self-esteem.
Physical self-esteem can greatly influence an adolescent's self-confidence, particularly during the pubertal transition when physical changes can be a source of either pride or embarrassment. However, given the complexity of human development, it's clear that a multifaceted approach is essential when considering the factors that shape self-esteem.
