loam

Explanation:

First Question (Which type of soil holds the MOST water?)

Soil water - holding capacity depends on particle size and pore space. Clay particles are very small, so they have tiny, closely - packed pores that can hold water via capillary action. Sand has large, well - connected pores that drain easily. Silt is in between. So clay holds the most water. The original selection of sand is incorrect.

Porosity is the volume of pore space. Sand particles are large and irregularly shaped, so the spaces (pores) between them are relatively large and well - defined. Clay has small pores, and silt is in the middle. Loam is a mixture. So sand has the greatest porosity, and the selection of sand here is correct.

Answer:

C. clay
