the best way to reduce the risk of being in an avalanche is to know how to avoid one.
skiers and snowboarders must be aware of snow conditions before going into avalanche terrain.
skiers and snowboarders should be able to recognize snow stability.

Explanation:

The details include taking avalanche safety classes (to learn avoidance), checking forecasts, and checking weather conditions—all related to avoiding avalanches. The first option, "The best way to reduce the risk of being in an avalanche is to know how to avoid one," encompasses these actions (learning to avoid, using forecasts/weather to avoid). The second option focuses only on snow conditions, and the third on recognizing snow stability, which are narrower than the overall theme of avoidance.

Answer:

The best way to reduce the risk of being in an avalanche is to know how to avoid one.
