Which one of the following statements is correct in describing Heisenberg's uncertainty (indeterminacy) equation?

A. The less precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa.
B. The more precisely the position is determined, the more precisely the momentum is known in this instant, and vice versa.
C. The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa.
D. None of the above

Can someone explain the answer to this question?

I believe the answer to this is C, because we can’t know both the position and the momentum precisely, and if we know one of them precisely, we cannot precisely know the other. Lavelle also stated that there is a limit on the accuracy to which the momentum & position of a particle can be known simultaneously, meaning that we basically can only be precise on one.

The answer is C, because you can not know both the momentum and position of an electron in an orbital simultaneously and if one is known the precision in which you can know the other decreases.
