• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (B)

Radar reflectivity depends on how big and how numerous the particles are, plus their dielectric properties. Large, dense targets reflect radar energy much more strongly, so they show up with the highest reflectivity on the display as red or magenta. Ice crystals, dry snow, and dry hail are typically smaller, less dense, or have lower dielectric contrast, so their echoes are weaker and usually appear in cooler colors (green, yellow, or orange) rather than the top-red/magenta range. Because not all of those precipitation types produce the strongest echoes, the statement is not correct.
