Handheld Showers Help in Preserving Safety in the Tub and Shower

Handheld showers help in preserving safety in the tub and shower in all of the following ways except they:

A) allow the person to control the water temperature and reduce the risk of a burn.
B) allow the person to direct the water flow, preventing a slippery bathroom floor surface for the post-bath transfer.
C) increase the individual's ability to wash areas prone to skin irritation and breakdown by focusing the water flow on difficult to reach body areas, such as the genitourinary region.
D) all of the above.
