Surface tension

a) will rise to maximum height.

The water molecules due to force of adhesion clings to the walls of capillary, and since the weight of water in capillary is all that the adhesion can support, the water height in capillary stabilizes.

But since weightless means, no such weight support, then the adhesion will dominate and the water will rise to the maximum height.
