Need Help: How tall should my Scope Rings be for AR15 A-3 flattop upper?

Just purchased from Midway a "DPMS AR-15 A3 Flattop Upper Assembly 223 Remington 1 in 9" Twist 20" Bull Barrel Stainless Steel with Free Float Handguard
Product #: 486925

How high should my scope rings be for a 3X9X50 1" tube scope? Don't want it higher than needed but no so low as to be unusable. I am looking at Burris or Weaver brand Picatinny-Style Rings. Any additional thoughts or suggestions would be great.

My choices are:

Ring Height: .520" (measured from base of ring to bottom of scope tube)

Ring Height: 3/4" (measured from base of ring to bottom of scope tube)

Ring Height: 1" (measured from base of ring to bottom of scope tube)

Thanks,

Lemmon
