Hi,
Nuclear fusion is the force that powers the Sun, the
stars, and hydrogen bombs, merging the nuclei of
atoms and not splitting them apart, as in nuclear
reactors.
(A) merging the nuclei of atoms and not splitting
them apart, as in nuclear reactors
(B) merging the nuclei of atoms instead of splitting
them apart, like nuclear reactors
© merging the nuclei of atoms rather than split-

(D) and merges the nuclei of atoms but does not
split them apart, as is done in nuclear reactors
(E) and merges the nuclei of atoms, unlike atomic
