Answer:
B). Colors have physical and psychological effects on people.
Step-by-step explanation:
Several types of research have exemplified the transitional impacts of colors on our mood and how we respond. This effect goes up to the extent of adjustments in respiration and blood pressure. It sounds a little strange, but that's true, people's mood is heavily influenced by colors and its combinations. The author in this excerpt demonstrates the physical and psychological effects of colors on people. He asserts the effects of color on human behavior and body. To illustrate: he describes that red color excites people and helps increase blood pressure while blue color offers a calming effect and pink improves the mood of people. Thus, option B is the correct answer.
