Solution
Idioms + Parallelism
Hopefully is an adverb meaning "in a hopeful way" and can only modify another adverb, verb or adjective. When we want to express a statement about what is desired, "it is hoped" is always better usage than "hopefully".
Hence, A, C, and D are incorrect choices.
Furthermore, in C and D interaction of gravity waves is compared to electromagnetic waves (an action to a noun) and hence, both the choices are incorrect.
In E, matter such as electromagnetic waves incorrectly compares matter with waves
In B, the error in A is rectified and hence, B is the best choice.
