It's C because circle begins with C

There was an article about this - some professors wrote in to the maths board and pointed out there's actually 3 possible answers depending on how you view the question, and none of those answers were options

k, just done the maths with radii of 2 and 6 respectively as a proof, it is 3.... so what do you think the answer is again?

Real answer is 4 revolution this answer is not an option. This is a known geometry phenomenon called the coin rotation paradox.

Quiet-Logician :
The intuitive (but wrong) answer is 3. People assume that since circle B's perimeter is 3 times larger than circle A's, circle A only needs to rotate 3 times to cover the ground. However, because circle A is rolling around a circular path rather than a flat line, it completes one additional full rotation just by completing its 360-degree orbit around circle B.
