A door size of 2'8", also known as "2-8", is commonly used for interior doors such as bedroom and bathroom doors. However, it may be too small for a room with a water closet as it is typically used for small spaces like a pantry or closet.

A door size of 3'0", or "3-0", is commonly used for standard exterior doors or larger rooms such as a living room or dining room. While it may provide enough space for a water closet, it may look disproportionate and unappealing in relation to the size of the room.

A door size of 3'2", or "3-2", is typically used for wider entryways or double doors. This size may be too large for a room with a water closet and take up unnecessary space.

The correct answer of 2'10", or "2-10", strikes a balance between being too small and too large. This door size is commonly used for smaller rooms like a powder room or laundry room, making it a suitable choice for a water closet.
