A) It would be doubled.
Why?
To answer the question, we just need to calculate the momentum of the basketball using the following formula:
[tex]Momentum=mass*velocity\\\\Momenum=1kg*12\frac{m}{s}=12\frac{kg.m}{s}[/tex]
Now, we have calculated the momentum and the result is 12 kg.m/s, what would happen to the velocity if we double the momentum? Let's calculate it!
[tex]Momentum=mass*velocity\\\\(2)*12\frac{kg.m}{s}=1kg*velocity\\\\velocity=\frac{24\frac{kg.m}{s} }{1kg} =24\frac{s}{s}[/tex]
Hence, we can see that if the momentum is doubled, the velocity will be doubled too.
Have a nice day!
