Answer

Choice C.

Work Step by Step

The Heisenberg uncertainty principle says that the product of the uncertainty in position and the uncertainty in momentum has a minimum value. Reducing the uncertainty in one quantity necessarily increases the uncertainty about the other. Any single measurement of position can be made to arbitrary accuracy, but this will necessarily increase the uncertainty in the measurement of the momentum and vice versa.
