Which of the following is not a part of drawing room?

A drawing room (living room) is the space in a home meant for seating guests and everyday relaxation, so it is furnished with seating and decor rather than kitchen or utility appliances used for cooking, cleaning, or ventilation.

Sorting each listed item by where it is normally placed: a piece of furniture meant for seating guests belongs in the drawing room, while an appliance for washing clothes and a kitchen ventilation fixture for clearing cooking smoke are both utility/kitchen items, not drawing-room furnishings.

Since two of the listed items fail the drawing-room test rather than just one, no single-item option can be the complete answer; the option that captures both exclusions together is therefore the correct choice.

Cross-check: reviewing the full list confirms exactly one item fits a drawing room (the seating furniture) while two do not (the laundry appliance and the kitchen ventilation fixture), so the option combining more than one exclusion accounts for the list correctly.
