plants, animals, tree roots
plants, cars, trees
rewatch

Explanation:

Biological weathering is caused by living organisms. Plants (including tree roots) and animals are living entities that contribute to it. "Animals and food" is incorrect as food isn't a weathering agent. "Plants, cars, trees" is wrong because cars are non - living. So the correct option is the one with plants, animals, tree roots.

Answer:

B. plants, animals, tree roots (assuming the second option is labeled B; if the first option is A, second B, third C, then it's B. plants, animals, tree roots)
