a. humus forms from fallen leaves, dead wood, and other dead organic matter.
b. tree roots break rocks into humus as they grow.
c. cold winter weather preserves humus in the soil.
d. dry conditions allow humus to form.

Explanation:

Humus is organic matter that forms from the decomposition of fallen leaves, dead wood, and other dead organic material. Tree roots breaking rocks doesn't form humus. Cold winter weather and dry conditions don't explain the formation of humus as directly as the decomposition of organic matter.

Answer:

A. Humus forms from fallen leaves, dead wood, and other dead organic matter.
