Which three main supports does soil give to plants?

Correct answer: Nutrients water and root support

The direct answer is option D: nutrients, water, and root support. Soil is more than loose dirt. It contains mineral nutrients, holds water, and provides a firm medium in which roots can grow and anchor the plant. Step by step: roots spread through soil; soil particles and organic matter retain water; dissolved minerals are absorbed by roots; the soil also holds roots upright against wind and gravity. Option A, colour, sound, and language, are not the three basic supports supplied by soil. Option B, road, water, and market, includes water but roads and markets are human facilities, not soil functions. Option C, air, moon, and river, does not describe the main support given by soil. Option D is correct because it names the essential physical and nutritional services of soil. Plants may also obtain some oxygen from soil spaces, but that does not change the best answer. Memory cue: soil gives roots “food, drink, and a hold.”
