constructive

The answer is D.) Constructive 

Constructive means helping to improve; promoting further development or advancement.

Let's take the root word of constructive. That would be construct. To construct something means to build or put it together.

Another example that might help the word make a little more sense is the term "Constructive Criticism". Constructive criticism is a term used when someone give advice or opinions on something to help improve it or make it more efficient.
