A1 is dribbling in A's frontcourt. A1 picks up his/her dribble and jumps off the ground in an attempt to release the ball for a jumpshot. A1 fumbles the ball while airborne (it slips out of his/her hand), and recovers the ball in (a) before he/she returns to the ground (b) after he/she returns to the ground and (c) after he/she returns to the ground and the ball bounces on the ground once.

Has A1 violated? And if not, what can A1 do now?

Please quote any rules and rule numbers/case numbers.

Thanks.
