Concept:Heisenberg’s uncertainty principle says the product of the uncertainties in position and momentum has a minimum possible value.Explanation:The standard relation is given by $\Delta x \cdot \Delta p \geq h$.Here, $\Delta x$ is the uncertainty in position and $\Delta p$ is the uncertainty in momentum.This means the product cannot be smaller than $h$; it is either equal to $h$ or greater than $h$.Therefore, the correct mathematical form is $\Delta x \cdot \Delta p \geq h$.Answer:Option C: $\Delta x \cdot \Delta p \geq h$
