After eliminating all AC for wrong usage of "hopefully" we are left with B and E.

Questions:

- If AC "E" was rephrased with the following, as electromagnetic waves do, will, it is hoped, enable, wouldnt the AC be correct?

- What is the difference between using "as" and "such as".

Is "such as" used as an "example" and "as" is used for comparison of clauses [Vs phrases, for which we'd use "like"]. Is that the crucial difference between "as" and "such as".

Yes, such as is used usually for listings of examples whereas AS or LIKE is used to point out differences/similarities.

E - such as EM waves do is not idiomatic. Also such as should only be used to list exmaples. However, we're not listing examples, but rather showing some similarity in their properties
in the way EM waves do vs like EM waves -> like EM waves is out. It compares action to a item (waves). So C and D are out.

Between A and B, I'll go with B. 'hopefully will enable' in A doesn't sound very right.

B for me.

A seems correct to me
Can somebody explain why the answer is B

i think its because of the way the word 'hopefully' is used...the phrase 'it is hoped' is more grammatically correct in this sentence
