In terms of nearness to the trunk, the antebrachium is to the carpal region.

The best answer to the question, would be: In terms of nearness to the trunk, the antebrachium is proximal to the carpal region.

Explanation:

In anatomy, we use certain terminology to be able to express where different anatomical parts of the body are positioned and located, related to others. Just like through the axes that are used to divide our bodies into sections, and these lines help us to determine exactly where a body part, organ, or region, is located in reference to others, we can also use central regions, like the trunk of the body, to mention the location of other parts in relation to it, and to others. The carpal and antebrachium regions are parts of the arms, and both, relative to the trunk, are distal, which means, far from it. But, when taking the trunk as reference, we talk about the location of these two parts in relation to one another, and the trunk we say that both are proximal to one another because they both are closer to each other than either one is to the trunk itself.

In terms of nearness to the trunk, the antebrachium is proximal to the carpal region.

Explanation:

"Proximal is used to describe a part that is closer to the trunk of th ebody or closer to another specified point of  reference than anotherpart (the elbow is proximal to the wrist)."
