What is the effect of a positive work environment?

Correct answer: Motivation and cooperation increase

The direct answer is option D: a positive work environment increases motivation and cooperation. A work environment includes the way people are treated, the level of safety, communication, fairness, respect and support at the workplace. When workers feel respected and secure, they are more willing to participate, learn, help others and complete tasks responsibly. The reasoning is: supportive conditions create trust; trust improves motivation; good communication encourages cooperation; cooperation can improve work quality and performance. Option D is correct because both motivation and cooperation are normal positive effects. Option A is wrong because meaningful work usually becomes clearer or stronger in a healthy environment, not weaker. Option B is wrong because stress does not always increase; support and safety often reduce harmful stress. Option C is wrong because a positive environment should improve safety rather than reduce it. The word “positive” is the exam clue: connect it with support, motivation, cooperation and well-being.
