Final answer:
The term 'medial' refers to the direction towards the midline of the body, making it the correct answer 'd) Medial' to the question.
Step-by-step explanation:
The term medial means the direction towards or near the midline. So, the correct answer to the question is 'd) Medial'. When describing anatomical positions in the human body, the medial direction indicates a movement toward the middle of the body. For example, the hallux (big toe) is medial compared to the other toes. This is opposite to 'lateral', which indicates positioning toward the side of the body, like how the thumb is lateral to the other digits. Proximal and distal refer to positions in a limb relative to the point of attachment; 'proximal' means closer, and 'distal' means farther away.
