Answer:
Clay soil
Step-by-step explanation:
We were told in the question about two samples of soil A and B. Sample B was confirmed to be loamy soil but it was discovered that sample A absorbed more water than sample B.
We now have to think about the kind of soil that has the greatest ability to absorb water. That soil type is called clay soil.
Clay soils possess a large surface area which is responsible for its ability to absorb more water. Hence, clay soil has the greatest water holding capacity.
