Concept:Collaborative learning involves two or more learners working together to achieve a common goal or complete a task.
Explanation:The question asks for the correct set of learning methods that involve collaboration.
Activity based learning requires students to work in groups, doing hands-on activities together.
Discovery learning encourages students to explore and find answers through group inquiry.
Learning through exploration lets students investigate topics as a team, using curiosity and shared effort.
All three methods naturally use group work and peer interaction, making them forms of collaborative learning.
Option A includes homework, which is often individual work. Option C includes solitary play, which is alone. Option D includes watching TV, which is passive and not collaborative.
Hence, only option B lists methods where teachers can form groups and assign tasks to be solved together.
Answer:B. Activity based learning, discovery learning and learning through exploration
