# The uncertainty principle states that (a) no measurement can be perfect because it is technologically impossible to make perfect measuring instruments. (b) it is impossible to measure exactly where a particle is, unless it is at rest. (c) it is impossible to simultaneously know both the position and the momentum of a particle with complete certainty. (d) a particle cannot actually have a completely certain value of momentum.

(c) it is impossible to simultaneously know both the position and the momentum of a particle with complete certainty.

Explanation:

According Heisenberg uncertainty principle, "it is impossible to simultaneously know both the position and the momentum of a particle with complete certainty".

ΔxΔp ≥ h/4π

where;

Δx is uncertainty in position

Δp is uncertainty in momentum

h is Planck's constant

Therefore, the correct option is "C"

(c) it is impossible to simultaneously know both the position and the momentum of a particle with complete certainty.
