Answer:
A. produce larger materials from the collision of smaller materials
Explanation:
The outcome of nuclear fusion reaction is that it produces larger materials from the collision of smaller materials. 
- Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of a large amount of energy. 
- The energy released provides the needed temperature for another set  of atoms to fuse. 
- This process in turn yields a bulkier material accompanied with the release of a lot of energy.
