Final answer:
The evidence weakly refutes Erikson because it didn't consider late adolescence and emotional changes that impact identity formation.
Step-by-step explanation:
The evidence only weakly refutes Erikson because it concentrated on the onset of adolescence and Erikson believed that an identity crisis was more likely to occur in late adolescence.
Erikson's theory includes the stage of identity versus role confusion, which is the main task of adolescence where individuals struggle to develop a sense of self. The evidence might not fully refute Erikson because it didn't consider emotional changes that could impact identity formation.
Therefore, option b) is most likely the correct answer as it aligns with Erikson's theory and the evidence's limitations.
