A. a life course perspective to define normal aging and to distinguish it from pathological aging.
Step-by-step explanation:
Continuity theory uses a life course perspective to define normal aging and to distinguish it from pathological aging.

This theory states that when aging people tend to continue with their familiar lifestyle, changes and adaptations are consistent with this.
