Question

1. a soils texture is determined by

mineral composition
particle size
type of humus
water content

Explanation:

Soil texture is defined by the relative proportions of different - sized mineral particles (sand, silt, clay) in the soil. Mineral composition refers to the types of minerals, not the size of particles. The type of humus relates to organic matter quality, not texture. Water content is about moisture, not texture. So the factor determining soil texture is particle size.

Answer:

The option with "particle size" (the third option from the top, with the label "particle size").
