Explanation:

- Option 1: Dahya

- Dahya is a name but doesn't have a specific known context.

- Option 2: Podh

- Podh, like Dahya, is a name but generally lacks further specificity or association with a group.

- Option 3: Koman

- Koman is a name that can be found in several cultures and may not be immediately distinguishable from the others.

- Option 4: Gotul

- Gotul is a specific system or institution found in some tribal cultures, particularly among the Muria people of India, used for youth education and community building.

The odd one out is clearly related to specific cultural practices rather than just being a name.

Answer: Option 4: Gotul
