Hanging ceiling hooks from concrete beams above drywall ceiling
You should not mount anything to the beam (A) by drilling in to it. Under load the bottom is under tension and the width of the hole reduces how much the beam can manage. Think of it as cutting a strand in a rope.
Theoretically you could saddle the beam with a strap, rope, chain, and cut out a section of sheet rock to allow for play, or have a brace made to provide a stiff point at ceiling level. This however is done at the expense of compromising the fire resistance of the beam and ceiling since you would be removing some fire barrier and adding a heat conducting medium saddled around a major structural component. A likely violation of your rental, lease, or association agreement in addition to your local building codes.
Consider having an assembly made that can be assembled below the ceiling. Something like either an A frame or a heavy gauged post mounted to a plate assembly. (Like much of the equipment at a gym)
