Which feeling does blue generally suggest?

Correct answer: Calmness and coolness

Blue is commonly associated with the sky, water, distance, and quiet spaces, so it generally suggests calmness, coolness, and stability. Therefore, option B is correct. Heat, fire, and strong excitement are more often represented by warm colours such as red, orange, and yellow. Although colour meanings can vary by context and culture, the question uses the standard elementary-art association.
