Hallo!

Approach: Being is "always" wrong unless it refers to human beings; so A & E are out

Between B & D, where the VERB is the subject, you should always prefer the Infinite mode with "TO" instead of the gerundive.

C is tempting, and I was unsure between C & D, BUT I notice that what "can give the edge" is not the advantage itself, but the fact that you INTRODUCE the product or process...therefore I opted for D

Moreover an infinitive is often preferrable as a "subject"

However, it's a tough one, according to me...

Stumped
Finally, I got confused between B and D. Wrongly selected B. Got the mistake from Carloblacksun's answer.
