What caliber is the M61A1 and M61A2?

Explanation:
Caliber is the bore diameter of the gun, or the size of the projectile it fires. The M61A1 and M61A2 are the six-barrel, Gatling-style aircraft cannon known as the Vulcan, and they fire 20-millimeter rounds. So the caliber is 20 mm. The other options correspond to different weapons with larger or different bore sizes, not the M61.
