Concept: Avalanches occur in snow-covered mountainous regions. They involve the sudden movement of snow, ice, and debris down a mountain slope.
Step 1: Understanding avalanche conditions.
Avalanches need snow-covered slopes, steep mountains, and unstable snow layers.
\[
\text{Avalanche} = \text{Snow + Steep slope + Instability}
\]
Step 2: Checking avalanche-prone areas in India.
Himachal Pradesh has snow-covered Himalayan mountains.
Jammu and Kashmir has high-altitude snowy regions.
Uttarakhand also has Himalayan snow-covered areas.
Step 3: Identifying the non-avalanche-prone area.
Western Ghats are not snow-covered mountain ranges. They receive heavy rainfall but do not have the snow conditions required for avalanches.
Therefore, the correct answer is Western Ghat.
