If a range hood is not adequately removing smoke and smells, the first things to check are the fan, grease filter, and ductwork. The fan may not be functioning properly, the grease filter may be clogged or dirty, or the ductwork may be obstructed or improperly vented. Checking these components can help improve the effectiveness of the range hood. The other choices (B, C, and D) do not pertain to the problem of smoke and smells not being removed from the kitchen.
