B) decrease.
C) not be affected.

According to the Heisenberg Uncertainty Principle, increasing the accuracy in measuring the position of a particle leads to a decrease in the accuracy with which its velocity can be measured. This principle states that the more precisely the position of some particle is determined, the less precisely its momentum (and hence velocity, since velocity is part of momentum) can be known, and vice versa.
