The majority of a grapevine's roots are located in which soil zone?

Explanation:
The majority of a grapevine’s absorbing roots are in the upper part of the soil profile because this zone provides the richest supply of nutrients and water from rainfall and is well aerated. Fine roots proliferate where organic matter is concentrated, which is mainly in the top layer, making this the primary area for uptake. Some roots do extend deeper to access water during drought or in very deep soils, but these deeper roots are fewer in number. Therefore, most roots reside in the top 50 cm of soil, which is why that option best fits.
