please select the best answer from the choices provided

Explanation:

Woolly lousewort is a plant that grows in cold environments. The dense hairs around its flowers act like a natural insulator. Heat from the sun is trapped by these hairs, which helps the plant in the cold climate. Moisture is not the main thing these hairs keep off. Caribou are not a common threat in the way described here. And the hairs are not mainly for seed - keeping - from - blowing - away (that's more of a function for some other plant structures like dandelion puffs).

Answer:

B. The dense hairs trap heat from the sun.
