The fundamental position is a specific body posture used as a reference in anatomy. It is similar to the anatomical position, but with one key difference in the upper limbs.

The fundamental position is a specific body posture used as a reference in anatomy. It is similar to the anatomical position, but with one key difference in the upper limbs.

In the fundamental position:

• The body is erect (standing upright).
• The feet are slightly apart.
• The head and eyes are directed forward.
• The arms hang by the sides of the body.
• The palms face medially (towards the thighs).

Let's evaluate the given options, assuming the options on the right side of the image (b, c, d) correspond to question 3:

• b) The body is erect and palms face medially This statement accurately describes the fundamental position, where the palms are directed towards the body's midline.

• c) The body is erect and palms face anteriorly This statement describes the anatomical position, where the palms face forward, not the fundamental position.

• d) The arms are extended away from the body This statement is incorrect for both anatomical and fundamental positions, as the arms hang by the sides.

Therefore, the correct statement regarding the fundamental position is that the body is erect and the palms face medially.

The final answer is $\boxed{\text{b}}$
