Answer:
A. hydrogen, which has an approximate mass of 1
(Photo for proof at the bottom.)
Explanation:
Fusion is the process of two nuclei joining together to form a bigger, more stable nucleus.
Hydrogen being produced from this process is not possible, because a hydrogen's nucleus only consists of 1 proton. 1 proton is the smallest possible nucleus. Combining 2 of the smallest possible nuclei will produce helium, which has 2 protons.
Here's a photo of Edge, good luck.

The element where nuclear fusion is least likely to produce is hydrogen, which has an approximate mass of 1
What is Fusion?
Fusion is known to be the act whereby two nuclei are said to be joining together to bring about a bigger and amore stable kind of nucleus.
