Concept:Slatted floors allow waste to fall through gaps, which helps with cleaning and hygiene.
Explanation:Slatted floors have gaps that let animal waste fall through.
This reduces the need for manual cleaning, lessening labour requirement.
It also keeps pens drier and cleaner, reducing odour.
These floors are built to provide a firm, comfortable surface, so they do not hamper animal movement.
Thus, statement III is false.
Statements I and II are correct.
Answer:D. I and II only.
