Scientists around the world have been working for decades on perfecting the process of nuclear fusion in the lab. Which statement justifies this research?

Scientists are looking for a way to generate an unlimited source of hydrogen.
Scientists are looking for a way to absorb the energy produced by nuclear bombs.
Scientists are looking for a way to produce the uncommon noble gas helium.
Scientists are looking for a way to create cheap, safe, and sustainable energy.

Scientists are looking for a way to create cheap, safe, and sustainable energy.

Nuclear fusion is the process by which two atoms rapidly collide at each other forming a new nucleus. The energy of colliding and synthesizing has intrigued scientist into believing that this could be one of best sources of renewable energy.

The reason why scientists around the world have been working for decades on perfecting the process of nuclear fusion in the lab is because they want to produce a way of creating cheap, safe, and sustainable energy - D. This is also what nuclear fusion would bring us eventually.
