B)greater than h
C)equal to h

The formula △p △ x ≥ h is Heisenberg's uncertainty principle from quantum physics. It states that the product of the uncertainties (or variances) in the measurements of two complementary variables, such as position (x) and momentum (p), cannot be smaller than a certain value (h-bar, which is a constant divided by 2π). Therefore, the correct answer is A, as the product of △p and △x cannot be smaller than h, which means they may be equal to h or greater than h, but not smaller than h.
