Why A is correct
For continuous kitchen exhaust, Table M1505.5 specifies 25 cubic feet per minute. The 100 cfm value applies to intermittent kitchen exhaust, so it is important to identify the operating mode. Larger rates can exceed the minimum; they are not the minimum asked for here. Check other equipment and installation requirements separately.
