Which of the following rewrites of the underlined portion yields a correct sentence?

This choice fails to provide a verb, making the phrase incomplete as a standalone sentence. While it describes the invention, it lacks the necessary structure to form a complete thought, leading to grammatical errors in context.

While this option includes a verb, it introduces a gerund phrase that does not clearly indicate an action or state relevant to the subject. It creates a passive construction that could confuse the reader about the main action in the sentence, thus failing to convey the intended meaning effectively.

This rewrite shifts the focus from the invention itself to the creators, resulting in a passive construction. While grammatically correct, it alters the original meaning of the sentence, which is meant to emphasize the invention rather than its inventors, making it an unsuitable choice.
