According to the opponent-process theory, cells that are stimulated by exposure to light are inhibited by exposure to light. yellow; blue red; blue blue; green yellow; green blue; red

YELLOW; BLUE

OPPONENT PROCESS THEORY OF COLOR

This theory suggests that we are able to perceive colour through 3 receptor complexes who oppose each other being the red-green complex, the blue-yellow complex, and the black-white complex.

According to this theory, there are cells that can only detect the presence of one color in the complex at a time because the two colors oppose one another. For example, humans cannot see a greenish red because the opponent cells can only detect one at a time.

Interesting theory but let me not digress. The blue-yellow complex oppose each other and so the first option is correct.

These years were the most productive in a man’s life. The slave traders also took into slavery 15-20 percent of the males under 15 years of age
