An abnormal drought combined with an extended period of hot weather can cause a wildfire in some of Earth's biomes. Which home would be least likely to experience a wildfire caused by these factors?

Desert

Explanation:

Desert are already experiencing long periods of drought and heat waves. Plants (mainly cacti) are sparsely grown in the biome and have high resistance to heat which makes it hard to catch a fire.

Since plants are sparsely dispersed around the biome, a wildfire even if started, cannot spread.
