The correct answer is A. A-horizon.
The A-horizon, also known as the topsoil, is the uppermost layer of soil and is typically the most fertile layer. It is the layer where organic matter, including decomposed plant and animal material, accumulates and mixes with mineral particles. This organic matter, commonly referred to as humus, provides nutrients and enhances the soil's fertility and ability to retain water. The A-horizon is usually darker in color due to the presence of humus.
