Explanation:
The correct answer is option D, "None of these."

Reasoning:
To understand why none of the given options is the correct answer, let's analyze each option in detail:

a) "a" English: This option implies that English is just one of the many universal languages. However, the given statement states that English is "the" universal language, meaning it is the only language that is universally understood and spoken by people around the world. Therefore, option A is not appropriate.

b) "an" English: This option also implies that English is just one of the many universal languages. However, as mentioned above, the statement implies that English is "the" universal language, not just one of them. Hence, option B is not appropriate.

c) "the" English: This option implies that the English language is specific to a particular context or situation. For example, "the English spoken in this region" or "the English used in this book." However, the given statement suggests that English is universally understood and spoken everywhere, not limited to a specific context. Therefore, option C is not appropriate.

d) "None of these": This option is the correct answer because none of the previous options accurately reflects the statement. English is indeed a universal language, but it cannot be described using any of the given articles.

In conclusion, the appropriate answer to the given question is option D, "None of these."
