a. monochromatic color scheme
b. diverging color scheme
c. sequential color scheme
d. categorical color scheme

Explanation:

A diverging color scheme uses two contrasting colors (like blue and red here) to represent values diverging from a central point (e.g., moderate temperatures, with blue for cooler, red for warmer). The chart shows cool (blue - toned) for winter, warm (red - toned) for summer, diverging from a middle (like spring/fall). Monochromatic uses one color family, sequential is a single - hued gradient (e.g., light to dark of one color), categorical is for distinct categories (not continuous like temperature). So the chart uses a diverging scheme.

Answer:

b. Diverging color scheme
