Choice C.

#### Work Step by Step

No external torque acts on you and the masses, so the sum of your angular momenta is conserved. The masses carry the same angular momentum right after they are dropped, so your own angular momentum is unchanged. Your angular speed is unchanged. Another way to see it is because you drop the masses perfectly vertically, no horizontal forces act on your arms and there is no torque that would tend to change your angular speed.
