How can a teacher help Aman who is struggling with complex problems develop problem-solving skills ?

The correct option is Encourage him to brainstorm and generate ideas.

To help a student develop effective problem-solving skills, a teacher should foster an environment that promotes critical thinking, creativity, and self-directed learning. Brainstorming encourages students to explore multiple perspectives, think flexibly, and try out various strategies to approach complex problems.

Why other options are incorrect:
- Tell him to give up on the problem: This discourages perseverance and leads to a fixed mindset.
- Discourage him from experimenting and taking risks: Experimentation and learning from trial and error are fundamental to problem-solving.
- Provide him with the answers: Directly providing answers prevents the student from developing their own analytical and cognitive skills.
