I guess of the choices, none ...
The Rolling Stones are without question the greatest Rock and Roll band ever. The Beatles would be the greatest Pop band. In reality, both defined their genres (yes, there were bands before in each "category", but not definitive ones.) Note : The Yardbirds, The Who, The Kinks, and Cream also receive high marks in the R&R pioneers category.
The greatest singular musical influence would have to be, hands down, Chuck Berry.
And the most important record of all time would have to be The Beach Boys' "Pet Sounds". It's the first significant example/use of "studio production", and as such was a major influence to the Beatles (Sgt. Pepper's), (The) Pink Floyd, and dozens and dozens of others (YES, Genesis, etc., etc.).
