Answer

Brief Explanations:

By observing the table, as the values representing spacing between joists increase (moving from left - right columns for a fixed load value), the values representing the maximum span for a given board size decrease. For example, when the load is 30, as the spacing values change, the span values get smaller.

Answer:

B. decreases only.
