A key characteristic of Self-Directed Learning is:

Self-Directed Learning is fundamentally characterized by the individual's ability to take charge of their own learning processes. The emphasis on personal interests and needs highlights a crucial aspect of this approach: learners engage more effectively when they are motivated by their own goals and curiosity. This intrinsic motivation drives them to identify what they need to learn, seek out resources, and determine the best methods to acquire new skills or knowledge.

In contrast, the other choices describe approaches that do not align with the concept of self-directedness. Solely relying on direct instruction limits learners' autonomy, while a preference for collaborative methods emphasizes group learning rather than individual initiative. Similarly, dependence on textbooks reflects a more passive learning style, where learners are not actively pursuing their interests but rather absorbing information in a structured way determined by others. Thus, the correct choice captures the essence of Self-Directed Learning by focusing on personal agency and motivation.
