The correct answer is A - leaves that close when touched.
The Venus flytrap is a type of flowering plant that is best known for its unique adaptation to trap live insects using a trap.
The trap is made up of two hinged lobes at the end of each leaf, with hair like projections called trichomes that cause the lobes to snap shut when prey comes into contact with them.
This type of movement is called thigmonasty which is a non directional plant response to being touched.

Explanation:
Although we tend to think of fires as a human invention that kills plants, animals, people, fire, as with rain or wind, is an essential natural component, basic to maintain the planet's biodiversity.
As for example, grassland ecosystems are also benefited by the same fires that allow renewal, and generate natural sustainability on the earth through the carbon cycle.
