This problem tests the use of comparison markers Like Vs As. In this SC problem the non-underlined portion has a clause, thus the answer choice requires the conjunction (comparison marker) "AS". "Like" is used to compare two nouns or noun phrases.

The expected use of AS in this SC problem is "X does/did something, just as Y does/did something"
e.g. Mary aced her LSAT exam, just as John cracked his GMAT test.

Here is the difference between D & E
(D) just as a spinning figure skater who increases speed by drawing in her arms
This choice only contains the noun phrase with "spinning figure skater" with modifier "who increases speed by drawing in her arms". Hence, the noun "spinning figure" is being compared with non-underlined clause "the buildup of ice at the poles and the drop in water levels near the equator speed up the Earth’s rotation". Hence its the improper use of comparison marker.
(E) just as a spinning figure skater increases speed by drawing in her arms
Correct. This choice correctly compares two clauses
- the buildup of ice at the poles and the drop in water levels near the equator speed up the Earth’s rotation
- just as a spinning figure skater increases speed by drawing in her arms

The main idea here is comparison between "build up and drop im water level speed up..." and "figure skating increases speed". So we can't use "like" since it is used to compare nouns. Between D and E the latter is better because E doesn't use "who" that is redundant

like is used to compare nouns only, but here it is compared to an action.

(B) like the increased speed of a figure skater when her arms are drawn in
same error as in A.

(C) like a figure skater who increases speed while spinning with her arms drawn in
same error as in A and B.

(D) just as a spinning figure skater who increases speed by drawing in her arms
as + noun is used to describe the role/function

(E) just as a spinning figure skater increases speed by drawing in her arms
correct

The comparison is between two 'processes'. So, 'like' is wrong. Now, only D & E are left.
D - Just as a F/S who increases the speed. - Process (speeding up the earth) compared with a person (F/S).
E - D - Just as a F/S increases the speed. - Process compared to process.

Point 1: Nicola Tesla was a scientist, not an example of radio

Point 2: Whenever we use a semicolon, the following clause should be an independent clause with an action verb.

(A) radio, such as Nikola Tesla ----- This choice makes Nikola as an example of radio.

(B) radio; including as Nikola Tesla --- we are using a semi-colon here and what follows is not a clause, because there is no verb for Nikola

(C) radio, including Nikola Tesla --- Now this choice uses a comma and a semi-colon. So, the following phrase starting with including, a modifier, is appropriate. Correct choice.

(D) radio; not least among them being Nikola Tesla -- No verb for Nikola in the latter part. A fragment

(E) radio; especially Nikola Tesla – No verb for Nikola in the second part.
