Nuclear fusion quiz [LVL 2+]

Hello there,
I made another quiz. This time it is about nuclear fusion. In fact, this quiz will be a part of a trilogy. Next one will be about nuclear fission and the third one about both. Many thanks to Oppenh4imer who checked and corrected the quiz before I posted it here.

The game I offer is Joe Dever's Lone Wolf HD Remastered.

The system is easy. All you have to do is to add one by one the correct numbers/letters of the right answers to the base address https://www.steamgifts.com/giveaway/ and add slash to the end. So that the final address would look similar like, for example, https://www.steamgifts.com/giveaway/C7bNV/

Level restriction is set to 2+. The size of letters does matter so think of it. I highly recommend using copy/paste (ctrl+c and ctrl+v).

PS: Don't forget to bump it if you like it.
PS2: if you want to know if there are some other quizes by me, check this list of all my quizes and jigidi puzzles.

What is nuclear fusion?

• H) Nuclear fusion is the separation of an atomic nucleus into two smaller nuclei.

Why have scientists been working for more than 50 years to try to create nuclear fusion power plant?

• E) There is excess hydrogen in our atmosphere that fusion reactions would use up.
• d) Nuclear fusion produces huge amounts of energy with little hazardous wastes.
• f) Nuclear fusion reactions are much easier to create in a chemistry lab than nuclear fission reactions.
