I'm trying to find out the correct answer from the dictionary which I provided.
I think it's the noun and the explanation is no.2.
"The extent or range of something's application, effect, or influence."
This is part of a catalog above a picture describing the company reaching its worldwide customers, so the sentence doesn't need a verb.
It's like "Apple, the master of cellphones".
So I need it to be like "(A company), reaching out worldwide"
