Final answer:
The anatomical position relevant to the question, in which the hands are facing palms forward, is defined as the body standing upright with feet parallel and the upper limbs held to the side.
Step-by-step explanation:
The anatomical position is a standardized method of observing or imaging the body that enforces uniformity in anatomical nomenclature. When a person is in the anatomical position, they are standing upright, with feet at shoulder width and parallel, toes pointing forward. The upper limbs are held out to each side, and the palms of the hands face forward.
If we consider the various options provided, we can determine that the body position that displays the hands facing palms forward is when the person is standing. This standard position is used to avoid confusion regardless of how the body being described is actually oriented. For instance, if we talk about an anterior feature of the body, such as a region on the wrist, we would describe it as being on the palm side when in this typical anatomical posture.
