Explanation:

The GMAT Sentence Correction test measures your ability to recognize grammatical errors, awkward phrasing, and awkward sentences. Here are a few rules to keep in mind while taking the GMAT Sentence Correction test:

1. Proper grammar and idiomatic usage: Ensure that the sentence has proper grammar and is written in an idiomatic way.
2. Concision: The best answer choice will be concise and avoid extraneous words or phrasing.
3. Parallelism: The sentence should have parallel construction, meaning that phrases or clauses in a list have a consistent structure.
4. Subject-verb agreement: The subject and verb in the sentence should agree in number.
5. Modifiers: Modifiers should be placed as close as possible to the words they modify.
6. Pronouns: Pronouns should agree in number with the nouns they refer to.
7. Idiomatic expressions: The sentence should contain idiomatic expressions that are commonly used in English.

These are a few general rules to keep in mind, but be aware that there may be exceptions and specific cases in the GMAT Sentence Correction test.
This line of reasoning can be in favor of the suggested linguistic alteration:

• Parallelism
• Considering two separate truths
• Modifiers

Given that, Captain James Cook, an English sailor, first saw the Glass House Mountains in Queensland, Australia, in 1770. He gave them their name because, according to legend, the mountains' jagged, damp rocks glistened like pieces of glass.
With this knowledge, let's explore the choices.

A: Incorrect

This choice is an incorrect one. Because of subject-verb agreement, answer option A is eliminated. The subject Mountains and the pronoun "its" do not agree in option A.

B: Incorrect

B is an incorrect choice. The passive voice is used in Option B. However, you want James Cook to be the subject of the subordinate clause, and "whom" is usually an object, therefore I eliminated this solution choice.

C: Incorrect

It is an incorrect choice. "Naming" seems to describe the entire main phrase, hence the correct answer is C. However, you want James Cook to be the person who named the Glass House Mountains, so I found this response choice to be illogical.

D: Correct

This is the correct choice. By whom is not an issue in B, as it refers to Cook, but the entire sentence is written in the unnecessary passive voice. It also distorts the meaning that James Cook purportedly named them and that their wet, bare rocks glistened like glass to Cook. D, on the other hand, does not permit such errors.

E: Incorrect

It is an incorrect choice. Because of subject-verb agreement, answer E is eliminated. The subject Mountains and the pronoun "its" do not agree in option E. Choice E's use of "it" as a pronoun also conflicts with the subject Mountains.
