This is a wonderful piece by the writer. We'd try as much as possible to do justice to it. So, follow me religiously as i take you through the analysis.

In the first response which is Option A, it could be seen that there is no clear distinction between the aim and the objective of the writer and the underlined words in the write-up. In the meantime, the solution here is very unambiguous because it does not connote any clear meaning there than what has been understood. Hence, it is INCORRECT.

On our way searching for the correct response, we are now visiting Option B in order to see what's in stock unfortunately, it didn't meet the standard required for the modernity the statement deserves. For instance, the use of ''which'' is unnecessary as it renders the statement an emphatic one. Consequently, it is also an INCORRECT Option.

Looking at this statement in this Option C holistically, we can see that the preposition ''to and be'' which suggest a future action. Contextually, a future tense word and a past tense verb ''was'' used is not in agreement with each other. It is INCORRECT.

This statement in Option D comes too easy, simple, unambiguous and less verbose. It connects with the mind of the reader so quickly and ensures that it is readable and understandable to a layman. It is indeed the Google we've been searching for. Clearly, it is CORRECT.

Here, in Option E there's too much emphasis on the keywords that arose from the use of auxiliary verbs and the modal verbs. It is however a correct statement and appropriately fitting. Nevertheless, the earlier shortcomings noticed would not allow it to pass for the most correct. Therefore, it is INCORRECT.
